Unable to run more than 1 tests set in a row on self-hosted runner

[KiritoMC03]

Hi! And thanks for your job!

Bug description How to reproduce

I have a self-hosted Ubuntu (server) runner that I'm trying to run tests of my project on. If I run the runner for the first time after installation, the tests run correctly. However, when I try to run them a second time, I get an error in the preparation phase of the runner. Deleting the _work folder helps me, but it doesn't look like a fix for the problem. The problem is reproduced if I stop and start the runner.

• Expected behavior

I'm expected to be able to run a lot of tests without errors or having to clean up the runner, as it works with github owned runners.
