Windows 10 Explorer crashes by working with files and folders

tucktuck2 · Nov 6, 2020

Hi everyone,

my windows explorer (Windows 10) is crashing most of the time by selecting multiple files or when I try to display the file/folder properties.

The Explorer is closing down then the Taskbar is empty and soon afterwards it is filled with th eicons again.

Error message from event viewer (german)

A few days ago always ntdll.dll was mentioned but now it is only shcore.dll

Unfortunatelly I only have a dump for the shcore.dll events.
