2021 Macbook Pro M1 Crashes when waking from Sleep and Requiring Password

panic(cpu 1 caller 0xfffffe001403b754): SEP Panic: :sks /sks : 0x00099775 0x000429cc 0x000429b0 0x0000b8f0 0x0000ec0c 0x00020574 0x0006e5f0 0x00061a40 [ppnnl]


File system is encrypted.


This error occurs after waking the laptop from some form of "sleep" (having had pressed the power button to make the laptop "sleep"), requiring a password to open the lock screen after it's awake. This is repeatable, though it now seems to require some additional time in sleep to recreate the crash (before I tried removing and reinstalling a suspected issue with Google Drive Desktop App, I could repeat the crash after just allowing the computer to 'sleep" long enough to cause the external monitors to go into power save mode).


What may be happening here?

MacBook Pro 14″, macOS 13.4
