2018 MacBook Pros crashing with "Bridge OS" error

Ok so today after many issues i went Mojave way 10.14 Beta (18A384a). I will keep you updated. Read a lot of messages Mojave can resolve a lot of MBP 2018 pains and i am happy to help beta testing - i thought myself, my machine is unstable on current public release so why not beta.. however, i am not going to use it for any professional work until everything is resolved.
I've been using Mojave for all of my coding since beta...3 I think it was? I haven't had any Bridge errors or any other problems. It's surprisingly stable for a beta.
Not here. Still KP once or twice a day. Every morning on wake I have a crash report, sometimes in the afternoon doing random things, like a watching a youtube video it will totally crash out, drop network connections inc. wifi, beachball and restart. I filmed it yesterday - might try and load it up on youtube.
Also - where I didn't have the speaker crackling at all for the first 3 weeks, I had it in iTunes 2 days ago out of nowhere.
Mojave has not fixed in my situation.
Unfortunately I was unable to install the supplemental updates from a couple of weeks ago for MBP's, they haven't come through for Mojave, only HS. They seemed to have solved some peoples issues over at Apple Support forums.

Just a warning for those upgrading to Mojave, Apple Support will greatly diminish unless you have plenty of supporting evidence these problems occurred previously under HS (reports etc.)
I got replacement two days ago. And got KP again before I implemented the supplemental update. It's CTO taking 2 weeks to get this and another KP is so hopeless... Anyways, it seems fine after the update now though, I will see over this week and if there's a single KP again, I will return it with no regret.

@fullauto thanks for info. I am aware of that fact, however, i am sick and tired of HS.. i was investigating much deeper how this system handles 8th gen of Intel CPUs, turbo and thermals, and i am so disappointed, it can not be worst.
@fullauto what is your beta version please?
However, "problems" with thermals are back on Mojave full blow. Just give it a try, do cinebench, second you will push run benchmark button, all 4 physical cores burn at 100 degrees. And i am running literary, bottom of the line
2,3 GHz Intel Core i5 with ridiculously low turbo boost... however, under HS i got kernel_task problem with 6000% cpu utilisation in case of anything mildly demanding was happening (i was installing Guild wars 2 just to see how it behave on CPU side, during installation kernel_task - 6000% mouse lag, system lag, video lag, beachball, again again again - yes it will stop after turbo runs out, but it really look like Apple have no idea when to utilise turbo and how to handle it on 8th gen CPUs - this was happening only AFTER supplemental update n.2 so i am assuming this has to do something with "thermal throttling fix").
I can report that in Mojave i do not have those problems with kernel_task killing whole machine out of nowhere with 6000% CPU utilisation.
Gentle-mans, more i investigate, more i am disgusted by whole MP 2018. I am in IT field for years from Customer care specialist, to SW and HW Testing specialist, currently QA manager for whole product line, i am working daily 8+ hours on PC or Mac, and i never, ever in my life had so much problems with single machine.
TBH i am not interested in replacement, this is, according to symptoms, clearly a SW issue. Just try to install Windows 10, rock steady, still funny thermals from time to time, but that is it (yes i know you can not utilise T2 fully under windows but still..it still should be utilised on some level as it should control many aspects of MP accessories )
This time, i am picking up red pill. I wanna see how deep rabbit hole goes...

@Broslowski - I was on PB 9.
Have just done a full rebuild back to HS, installed supplemental update. Set-up again as new with no data migration. Has taken about 6 hours, all going smooth so far.
Fingers crossed for both of us

I think you still will have the BridgeOS firmware from the latest beta installed, even though you do a full reinstall from scratch to High Sierra.

any way how to got latest BridgeOS on Mojave? So far i reported issue i am able to reproduce 100% time - while realtime data encryption is in place (syncing iPhone via iTunes - backing up device) sound output will shutter during period of data transfer.
Firmware once updated, won't be rolled back with the OS. Check your BridgeOS firmware version and it should be the same as the latest update you did.
Me too and the beta firmware followed me all the way back into High Sierra.
I was considering doing something similar, I did it after the first supplemental update and it didn't really help. I've just been living with this, flaunting my laziness and masochism@Broslowski - I was on PB 9.

Does closing the laptop lid count as "sleep"?
I almost never use sleeping on my Windows machine, however I close / open lid here and there, without turning off, for example when I need to carry it somewhere.
Does closing / opening the lid cause it to crash?
Or something else?
It depends on how you have your laptop set up. On both MacOS and Windows, you can change what closing the lid does, and I know on my Windows machine at work you can have it set differently based on whether it's on battery power or plugged in.
But the crashes I experienced weren't based on closing the lid; it was always while it was asleep. Sometimes lid open. Sometimes in clamshell mode connected to a monitor, and sometimes lid closed. But so far my KPs have ceased, ever since the 2nd supplemental update.
BridgeOS Firmware is 16P375 in Mojave 18A389. I have a 2018 15" and have not had any issues with any OS version I've run on it (HS, Mojave betas), so I have no way of reporting if any issue is resolved.
