Crashes with 'too many open files in system'

[HansKre]

Describe the bug

When changing git branches and installing npm dependencies, I am regularly seeing this error:

After that, my terminal hangs and other applications, e.g. Chrome, Teams crash.

To Reproduce

Following error happens only if zsh-autosuggestions is enabled.
Use VScode's built-in terminal.

# checkout an old git-brach with many changed files
% git checkout feature1
% rm -rf node_modules && npm i
# ...

% git checkout feature2

Expected behavior

Should not produce 'too many open files in system'-Error.
