Sleep transition timed out after 180 seconds while notifying clients about upcoming system capability changes.

My MacBook Pro keeps crashing when trying to go into sleep mode. I also keep getting the same error message:

Sleep transition timed out after 180 seconds while notifying clients about upcoming system capability changes. Suspected bundle: com.apple.iokit.IOGraphicsFamily. Thread 0x74.

Any help would be greatly appreciated.

iMac 2017 with sleeping sickness! Hi everyone, I have a 2017 iMac 21.5” which has been working great lately. I upgraded to Ventura a couple of weeks ago and that seemed to go well. Earlier this week we had a power outage. When I switch on my iMac now it constantly goes sleep. It will sleep while doing the initial boot before it gets to the login screen. Then when I wake it the login screen appears and I can log in. I then get between about 3 and 20 seconds before it goes back to sleep again. So far I have reset the PRAM and SMC but neither had any effect. Is there anything else that I can try? Thanks in advance and happy holidays to all!

Rebooting & Touch Bar Crashes after Ventura update Hey Everyone, After updating to Ventura, my Mac Pro 2019 occasionally restarts after a suspected problem while on sleep mode and the touch bar disappears. I keep sending the crash report to Apple so hopefully on the next update they can fix the issue. For the moment what works is that I have to keep reseting the SMC but it's such a pain, and it keeps rebooting every so often
