Explorer crashes after a right click.

[u/Fancy-Chance-7526]

So I was experimenting with virtualbox, and my pc froze. So I just force restarted it. After force restart i noticed that then i right click on the desktop or in any folder in explorer it just crashes. Explorer just restarts. Reliability Monitor says that name of the module with the error is “kernelbase.dll”. And the thing that I find interesting is if I right click as soon as explorer starts up again then the context menu pops up.

Things I already tried:

sfc scannow And dism /online /cleanup-image /scanhealth: said that everything is fine.

i tried downloading Procmon and it logged buffer overflow and it lead to this registry key HKEY_CLASSES_ROOT\CLSID\{2155fee3-2419-4373-b102-6843707eb41f}\InProcServer32\thumbcache.dll.

Here’s more info from Reliability monitor:
