Our Azure DevOps pipeline seems to fails after executing exactly 21 tests. It seems like there is some invisible hard limit that's stopping execution after 21 tests. It was working last week with no changes made between then and now. I can't seem to figure out the issue so I thought I would try my luck here.
Here's the output of the failure: (Can't seem to post the full output so here's the relevant portion)
