Hi @金欢 李 ,
Welcome to Microsoft Q&A!
Have you tried to run your Visual Studio in safe mode and check if the situation disappears?
Have you installed any antivirus software? Please temporarily disable them.
Please try to enter “devenv /ResetSettings” at Developer Command Prompt to restore your Visual Studio default settings and check again.
Meanwhile, you can also clean your %temp% folder and delete the hidden .vs
folder.
Sincerely,
Anna
