Not able to create the bug. Can you verify the steps again, anything you have done before you got the issue?

With the steps, you mentioned to reproduce, the bug is not happening.

I can reproduce it both office PC and home.

1. Open vscode, a file is already open(test.cu or Untitled-1).
2. (Option) Check ctrl + ` works fine(open and close terminal)
   3.. switch to other window and reopen vscode window
3. Ctrl + ` not response.

Funny that

1. Open vscode with Default page(show all cmd, open file, etc.).
2. switch to other window and reopen vscode window
3. ctrl + ` response once(open terminal once).

Switch to any windows is reproducing. I tried chrome, windows setting panel, etc.

@illava I cannot reproduce. ctrl+` works reliably for me, even if I focus another application and return to VS Code later. Do you happen to use a specific keyboard layout where this reproduces?

[illava]

I figure out the issue is related to IME(QQPinyin). Repaired after uninstalling.
Thanks for your help.

That‘s why it appears only my home and office PC.
Don't know what's the exact problem with IME. Since it is rare used and lacks feedback methods. Simply change to another IME will be fine.

Ok, it seems that you have a similar issue as #70482 . ctrl+` is simply reserved and used by the IME, therefore the keybinding does not reach VS Code.
