Got this error "java.lang.RuntimeException: no such class" when import extension

[Ove_Halseth]

Found a workaround in this thread:

Java Error Error from Companion: java.lang.RuntimeException: invalid syntax in eval form: :8:1: caught exception in inliner for # - java.lang.RuntimeException: no such class:

Is this for PC?

It's apparently a bug, and the workaround is to load your app in AI Companion first. After that Emulator will work for that session.
