Steps to Reproduce

1. start debug session
2. merge branch while debug session running

Would also be thrown if there is an intended application shutdown initiated that triggers Application_OnEnd.

Actual Result

Thanks for raising this. It came up through #1157
We're looking to add a fix soon but it would really help us/speed it up if we'd get a PR with a fix
