Random crashes with FileNotFoundException

Describe the bug

Sometimes Stryker crashes for random projects with this error

This happens after throwing a bunch of exceptions with the FileNotFoundException on the top, see logs attached. The process exit code is -532462766.

It’s important to say this is by far not deterministic. I get a feeling we have this once every 10 times or so. I have just run Stryker against the same project 20 times and it failed 3 times with this thing.

Logs

Here are the logs: logs.txt

They are pretty similar for these crashes. Once the log also had this attached at the end of the call stack (just before Time Elapsed TIME):

Expected behavior

This shouldn’t happen.

Desktop:

• OS: Windows
• Type of project: observed both for net5 and netcore3.1
• Stryker Version [e.g. beta 0.22.9]

So, looks like this has entirely disappeared since we moved to Stryker 1.0. Target framework is most probably unrelated, we’ve run Stryker against the whole code base a few times between moving to 1.0 and specifying the target framework.

So anyway - good stuff 😃 I’ll close the issue then.

Hmm hang on, we’ve just moved to .NET 6 and C# 10 so have a lot of bigger issues related to that - but I will update this ticket once things stabilize a bit 😃
