Just a thought.
This is for 2010 MBP - officially on High Sierra. But you are on Catalina, with some patch? Possible bad interaction with OCLP build?
Possible to unpatch/revert back to High Sierra?
Start from a known state?
Got a tip for us?

Since I swapped my SSD (which holds Catalina) with a completely empty HDD, which now sits in the internal SATA slot, there should not be any interference :/
Prior, is that where you installed OCLP and build the EFI?
The prior patch (to run Catalina), did that modify firmware?
Did you revert back to stock firmware? Did that firmware then get updated to latest with High Sierra Sec Update around Jul-2020?
Correct, I used my Catalina installation to download OCLP and Monterey to build the installation USB stick. When I had the stick, I took the SSD out of my MBP.
Catalina was once installed using Dosdudes Patcher, so I assume that the firmware remained unmodified.
I did neither reverted any firmware, nor went back to High Sierra.

A reminder - each macOS on a separate partition and OCLP will boot it no matter what method was used to install. Works as intended. 
And SHRIEK! this works perfectly w/o patching the bootROM!

Update to OCLP 0.4.2 MBP 8,2 Early 2011 and Monterey 12.2
Firstly, thank you to all involved in this project from Ausdauersportler to Khronokernel, and all the others. Keeping theses machines going is a positive for our environment.
1. Very stable with OCLP 0.4.2
2. Post install volume patch identifies video card and updates to legacy cards ie. wifi
3. All programs run without incident
4. Display brightness adjustable
5. No airplay/airdrop (expected).
Does anyone have suggestions for running airplay with this configuration?
Thank you for your assist

Oh crap, yes that's what I was trying to say, got Apple's cutesy names mixed up ? Thank you for correcting me.
So I guess I'm asking again, will it work?
EDIT: nevermind found my answer

For those who use gibmacOS it is fixed and will install python3 that was removed in beta 3

Yes, definitely try a different USB stick!
I know that the "last minute" can take several hours on old machines - especially with rotational hard drives...
Defective RAM modules could also cause problems like this...
AirDrop needs a BT 4.0 WiFi ac upgrade
AirPlay - if ever working - would need the patching in of High Sierra HD3000*, AppleIntelSNB* extensions and bundle files, AppleGVA.framework and Catalina AppleGVACore.framework
We tried and it did not work post Catalina except once on an iMac12,2 running Big Sur with HD6000. There is a post about it on the Big Sur thread.
Under M. change the version to 10.16 to see all of the avail. updates. Thanks for the tip TimothyR734. ?Fort hose who use gibmacOS it is fixed and will install python3 that was removed in beta 3
Hello
I installed 0.4.2 over my 0.4.1 on monterey 12.2 on my mid 2014 mbp
and now receiving the following message when booting “This Mac OS X is not supported on this platform”
I think my mistake was to tick the option for “Allow for Native Models” which now causing this
is this error reversible ? how it can be fixed ? or I need to go the Hard way and format ?
can I load OpenCore from recovery/terminal and build with correct settings again ?

Thanks man, but I am still on Catalina, it would be my first update...
New feedback: Reverting my White MacBook (Late-2009 MacBook6,1) with NVRAM/SMC reset back to latest official supported macOS (High Sierra 10.13.6 installer from Apple Homepage) and the two last High Sierra Security Updates (2020-05 with 2.4GB and 2020-06 with 1.2 GB) installed a new firmware (now 209.0.0.0.0 superseding MB61.00C8.B00/B02). After downloading new full install package of Monterey 12.3 developer build and OCLP 0.4.2 final release I've created a new USB drive with OCLP patched macOS installer.
Now everything is working as fast as with Monterey 12.2 final before.. The Control Center sliders bug is still present after applying non-Metal acceleration patch (it's only cosmetic and a known bug - no problems using the sliders). I'm happy (if hibernation bug is also fixed now) - AirPlay with second Monterey Mac is working too! I will test SideCar next - unfortunately I need to get an iPad for this...
Really great work ? - I only found some smaller bugs (like keyboard setting switching automatically from "German Apple layout with @=Alt+L" to "German Standard layout with @=Alt+Q" after installation of Monterey is finished - can be switched back in keyboard settings) right now...

Do you have another Mac to install OCLP on a USB pendrive? (Remember to adjust the settings to your target Mac.)
Ahoy!!? NEWBIES -ATTENTION!! Before asking for help, please cite the Mac you require help with in your signature! Much appreciated.
Make certain FileVault is OFF! Install a previous version from USB, first. Preferably on it's own partition.
Hey all, I switched a 2011 Macbook pro 8,2 to 2012 logic board but it still has the original wifi card. So I patched Monterey OCLP 0.4.2 on this as a macbookpro9,1 of course but the wifi patch isn't there for the 2011 wifi card. Is there an easy way to patch that manually? I'm not seeing a separate setting for wifi. I was going to use barrykn micropatcher to fix the wifi but I believe that won't work unless it sees a patched Big Sur installation.
As it stands the wifi option is missing from network preferences and there is no option showing to re-add it back in, otherwise I would've set up the wifi manually at least.
*Update* This turned out to be an actual hardware issue and wasn't related to the patch. The 2012 board I used was discovered to be damaged and required a component to be soldered on.

Always worthwhile getting the latest correct firmware onto the old machine.
Am sure you are happy it fixed some issues.
I had some
edit - I forgot, it was airdrop issues not airplay.
