Hello @forki, I think you have this problem because of a bug in async prior to Fable [5.0.0-alpha.11](https://github.com/fable-compiler/Fable/releases/tag/5.0.0-alpha.11). Before that version, the exception inside of async were not propagated correctly....

I could back port the fix to Fable 4, would this work for you?

@forki Sorry took me sometime to make the release because of a bug with .NET 9 being available now... This issue should be fixed in Fable 4.25.0

That's strange perhaps I didn't back-port the complete fixes 🤔

@Jand42 I have a hard time trying to make a reproduction code. Would you be open to have a call together to try to diagnose the problem as you are...
