unworkable slow

Type: Bug

Afdter working some time in vs code, opening files is VERY slow. Unworkable. On that moment its also slow in visual studio. It looks like Git is the reason but not sure.
closing vs code takes very long Get the message "Backing up editors with unsaved changes is taking a bit longer" followed by the message "closing the windows is taking a bit longer".
Restarting vs code doesnt help. It takes ages to reopen(first open was no problem,)
Pc itself works fine on that moment.
Restarting pc helps (for a while).

VS Code version: Code 1.135.0 (08d4889f9ec4a1685d257b9b95de036c8e1ce1e5, 2026-08-25T14:26:52Z)
