Hello
Starting from yesterday (i.e. 12 h ago) I'm experiencing the problem when starting backtest of my projects. The process stucks in state "Launching Backtest" and never moves forward (see screenshot below). Same behavior on all my strategies. I also tried to cancel backtest and start again - no luck.
Any ideas how to fix this?

Hi QC Support,
I think I found where can be the issue - check please this my test project. This is a default one - I just clicked “+ New Algorithm” - and it runs just fine.
BUT! When I added a test parameter - I was able to reproduce the issue: on startup the backtest got stuck. I removed the parameter - everything works fine again. I also tested on my other algos - got same behavior.
Can you please look into this?

Sorry there was an issue with projects with parameters. We fixed the issue and they're now running fine. We've installed new tests to prevent this from happening again.
Best,
Jared
