iMac 2017 won't wake from sleep, multiple restarts required (error log attached)

[will0407]

My Dad's 2017 imac regularly fails to wake from sleep or spordically restarts when in sleep mode. When we have to force a restart, it doesn't always get back to the login screen first time round, it'll often hang on the loading bar to the point where we have to hold the power button down again to switch it off/on.

EDIT
I've attached the panic log from 14:11 today (17th June). Any help/info greatly appreciated.

Running 10.14.6

I've had that exact problem happen with 10.14 on my 2017 iMac as well, and in addition to the updated and thereby broken Bluetooth stack it was one of the main reasons why I skipped Mojave altogether and went straight from High Sierra to Catalina.

Thanks for the reply. Will probably try updating to big sur this evening.
