The tests were working normally for a few days, it suddenly stopped working, the tests did not run anymore.

Displays message done but always stays 0/1, and when I try to run a test suite it generates the following error.

Could you share the test script and where the error happens?

This error only displays when I run a test suite. If I run a test case it does not run, I can by only a WebUI.openbrowher that it will not work.

I restored my windows to a point that worked to resolve.
