• OS Version:

macOS Big Sur
11.2.3

• Problem
  If using code . (command line), this issue is not present.
  If starting VSCode from e.g. macOS Spotlight, BBEdit will fail with this error:

$ git -c core.quotepath=false -c color.ui=false difftool --no-prompt --tool=bbdiff -- app.py
You must allow `bbdiff` to send events to the BBEdit application.
Use `tccutil reset AppleEvents` to reset the system's permissions, and try again.
bbdiff: error: -1743
fatal: external diff died, stopping at app.py

Steps to Reproduce:

1. Use a git project, e.g., git clone https://github.com/alanwilter/flask-pytest-example
2. Add to your ~/.gitignore:

git config --global diff.tool bbdiff
git config --global difftool.bbdiff.cmd 'bbdiff --wait --resume "$LOCAL" "$REMOTE"'
git config --global difftool.prompt false

2. Start VSCode via Spotlight
3. Change file app.py and save it.
4. Open a terminal (cmd-J) inside VSCode
5. Run this command:

git -c core.quotepath=false -c color.ui=false difftool --no-prompt --tool=bbdiff -- app.py

Does this issue occur when all extensions are disabled?:
Can't test this way.

• Possible Solution:
  Please see "Open in BBEdit" repository command fails desktop/desktop#9050 for details but, essentially, VSCode is using the macOS Hardened Runtime, but does not have a code-signing entitlement to allow it to send Apple Events to other applications.
