I upgraded to 1.1.43-IC-2021.1 this morning and now get this error when opening a project that uses KoTest.

I’ve removed 1.1.43-IC-2021.1 from the plugin store, so if you uninstall, restart, and install, you’ll get the prior version. That should work and if not I can push out a fix later but JB take 1-2 days to approve plugins.
