Thanks for reporting! Any chance you could share the problematic code? If not we will only be able to add a condition, but not fix the underlying issue.

commented

The code changed quite heavily around that parts, we should wait for 3.3.3 to confirm that the exception is no longer being thrown.

commented

Thank you for checking it.
I will see if the issue is resolved after Scala 3.3.3 or 3.4.x release and report the result.

commented

I tested our project with Scala 3.4.0-RC1, and the issue has been resolved 🎉
