I've had no clue what's the problem is until I found this in event viewer.

While it's dotnet problem FSC should be less error-prone and do not crash randomly.
But catch exceptions at the highest level and report them clearly.

FYI, problem with dotnet8 is caused by setting DOTNET_SYSTEM_GLOBALIZATION_INVARIANT to true.
But it's not related to this ticket directly. It's just example of system failure which FSC hides and makes hard to understand.
