Win 11 Crashing - Probably Excel Related

updated to 26.4.0 (57513) and it crashed with BSOD 3 times today...
3rd one was UNEXPECTED_KERNEL_TRAP, 2 before are
CRITICAL_STRUCTURE_CORRUPTION

 

Thank you, I hope that goes well.
I have not used the machine enough since upgrading to 26.4 to notice any trend although yesterday I came back from lunch to find that Windows had rebooted.
That is different to before, as previously it always crashed whilst I was working in it (usually Excel) and also it would just leave me back at the Mac desktop. Of course yesterday could have been coincidental.

I am also following this interesting thread, which I presume may be related:
