Also happens on current 2022.1.2 (Ultimate) version, build #IU-221.5787.30

I do see only the first exception from @carlosrafaelfernandes in the stack-trace, though (not the original one from @Bbbrinks or @trailsnail:

Essentially this means the plugin is unusable on any reasonably current version.
