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]
