System restore failure after Avast update

[REDACTED]

Hi,

I was updating Avast and after that my Windows 10 hasn't been able to start any more.

It prompts into system restore but I always get the appxstaging error, even if I chose older restore points.

I can't even boot into safe mode.

You got any hint?

Thank you!

download the media creation tool

burn the iso and boot or boot it up using a flash drive
choose startup repair
if it doesnt work try the advance settings.

I could manage by deleting WindowsApp directory thru command prompt.

Thanks all the same!
