We often seem to get a "Cannot load model" error in Power BI Desktop which is impossible to get rid of - you need to open the Task Manager and force close the whole application (potentially losing work etc.).
I have reported this issue internally: CRI 137947129. Will update here once I get any information.

I got information that "It is a known issue but solving this is a lower priority for the team. We do not have an ETA when this would be fixed.".
