I can back it up. VSCode 1.81.0 and extension 1.5.3. I see a sensible freezes with 2000 closing brackets. The more brackets, the longer the freeze, up until:

[Window Title] Visual Studio Code [Main Instruction] The window is not responding [Content] You can reopen or close the window or keep waiting. [ ] Don't restore editors [Reopen] [Close] [Keep Waiting]
