i've had these crashes on my refurbished m1 mba - what's wrong?

I recently got a default spec m1 Macbook air from the refurbished store, about 2 months ago.

Since then I've had some crashes - I am a bit worried, as I don't think a device should be crashing

I saved two of the crash reports / logs

Can somebody help me find out what's wrong?

Thank you!

Verify your software is up to date macOS 11.6 —

Can you run the user Diagnostic...not as definitive as Apple's own AST2 (Apple Service Toolkit) back bench diagnostic, but may kick out an error code.
