I've found that taking a few minutes to double-check the settings and prerequisites before troubleshooting deeper issues can save a lot of time.

I’d also suggest documenting the assumptions and constraints alongside the main analysis, even if they seem obvious at the time. A few weeks later those details are usually what explain why certain decisions were made, and it saves a lot of backtracking when the model evolves.

I had a similar problem before, and in my case it was caused by an outdated dependency/config file. After updating everything and clearing the old cache/temp files, it started working normally again.
