Intellij IDEA 2021.2.2 can not lunch after Copilot update


I just updated Copilot via IDEA and then Intellij IDEA stoped working.

I face an error message when I try to start the app.

The full error by commend line:

CompileCommand: exclude com/intellij/openapi/vfs/impl/FilePartNodeRoot.trieDescend bool exclude = true
