This is a regression from the range PR, if that can help locate what may be the issue.
I'll take a look!
I also saw this InvalidMethodReceiver and I think it is connected to static dispatch. When I replaced all static dispatch to normal function calls, the error went away.
https://github.com/roc-lang/roc/pull/8578 should fix this one
btw thank you @Matthieu Pizenberg and @Fabian Schmalzried for all the bug reports - they are extremely helpful! :smiley:
