Hi everyone. I'm having a problem in the Algorithm Lab where after trying to execute a backtest, after the 20 second delay timer, I'm brought back to main.py with no warning or error message. Is this happening for anyone else?

Hi Andrew,
It seems like you're experiencing an issue with backtesting in the Algorithm Lab. There could be several reasons for this, and it's hard to pinpoint the exact cause without more information. However, here are a few things you could check:
Make sure your algorithm compiles correctly. If there are any errors in your code, the backtest might fail to run. You can check this by looking at the build output in the Algorithm Lab.
Check if there's an issue with the data you're using for backtesting. For example, if you're trying to backtest on a symbol that doesn't have enough historical data, the backtest might fail.
There might be an issue with the backtesting engine itself. In one of the discussions on the QuantConnect forum, a user reported a similar issue and it turned out to be a temporary outage of the backtesting system. The issue was resolved by the QuantConnect team.
If none of these suggestions help, I would recommend posting a detailed description of your issue on the QuantConnect forum. The community and the QuantConnect team are usually very helpful in resolving such issues.

I've not been able to run any backtests for the last ~18 hours - on any code. Maybe the system is down?
