I have a grey screen. My Mac did an update but then blacked out at once while I was on a google call.
What update and from what version to what version? macOS update or an app update? If an app update, again which app and versions are involved?
Can you boot your Mac at all? Can you access the Apple Silicon Mac's recovery mode Options screen?
Startup key combinations - Apple Support
If so, then you have a different issue than the OP who cannot do this on their laptop. If you can do this, then try booting into Safe Mode.
You should probably start your own thread since your issue may not be exactly the same as the OP's and if the issues are different, it will just confuse everyone reading this thread. If you can boot your Mac normally or into Safe Mode, then run the third party app EtreCheck and post the report using the "Additional Text" icon which looks like a piece of paper. If you can do this or access the Options boot screen, then please start your own thread since it would indicate your issue is different than the OPs since they cannot do any of this with their Mac. When starting your own thread, please provide the answers to the questions I've asked and posting an EtreCheck if possible.
Make sure to disconnect all external devices from the Mac in case one of them is causing a problem.
