Windows 11 – buggy

Hi,

I took the prompt to upgrade to WIndows 11 this week. I’m finding it all quite buggy:

Widgets opens then crashes out, Meet Now/Chat won’t open, Teams crashes out, WhatsApp desktop won’t open, Messenger won’t open.

I’ve tried a Windows repair (with keep my files option), sfc /scannow and various other options. Has anyone else come up against this? The laptop previously ran Win10 really well, naturally.

Ta.
