If you haven’t already, try deleting your current installation and reimporting it :+1: Namely because 5.2.2 was a version that required a full reimport.

Hi

Would it be possible for you to disable the burst compiler and try again? That might produce some more detailed stack traces.

Hi

I have managed to replicate this. A fix will be included in the next update.
