.Net Version

Reproduction Steps

Reproducible with CefSharp.MinimalExample since 120.1.110 (cefsharp/CefSharp.MinimalExample@136a65e).
Just launch the application twice.

Expected behavior

A second launch of the application should be possible (without any restrictions).

Actual behavior

A launch of any more instances result in a crash.

This is the output of thedebug.log from the second launch:

[0109/101550.289:ERROR:crashpad_client_win.cc(143)] crash server failed to launch, self-terminating

This was working with v120.1.80.
