M1 MacBook Pro - Kernel Panics and auto shutdown

My machine is randomly crashing and shuts off completely such that even when I connect the charger its not showing the charging indicator

A few days ago, I had seen a similar and had taken device to apple support center. they ran a comprehensive hardware diagnostic test and found no issue.

I saw a similar issue yesterday and I am not sure what is causing it. I re-ran the diagnostic test and same no issue was found in hardware. I ran "EtreCheck" and it did found kernel panics found below

2023-07-18 19:31:48 Kernel Panic (2 times)

What should I do because the apple support is asking me to erase and resin tall macOS in the hopes that my issue will go away even without looking at this kernel panic that I have been requesting Apple's technical team to look at.

Can someone please guide me to isolate this issue and tools or mechanisms to fix this

Hi,

Try to start up in Safe Mode, then normal boot could solve your issue. I think it's a software related issue.

Start up your Mac in safe mode - Apple Support

If it doesn't help, shutdown completely then normal start up could solve the issue(resetting SMC).
