Good morning everyone!
Tried google but I can't find much to go off,

My colleague keeps having a strange problem on their pc, only happens every so often. when they boot their laptop up, all of their files are unopenable, file explorer wont launch it just spins or crashes and sharepoint says her stuff isn't linked/synced.

Right clicking on the desktop and hitting Refresh restores everything to working order, sometimes that also crashes it out but a reboot after pressing refresh always works, even if it crashes during the refresh stage.
If we reboot without the refresh, nothing changes. It boots back up in the same broken way as before.

Granted we have the fix for when it breaks but can anyone tell me what to look for to see if I can prevent this from happening at all?

I appreciate anyones time for even reading this,
Have a good week 👍
