IllegalStateException (loader constraint viloation) when analyzing, new in 1.20

I had no issues with 1.19, but I’m getting this now. Running 2022.1 on a mac.

[DeMack]

I should probably add, since it might not be clear, that this prevents the plugin from working (i.e., nothing is annotated in the editor).

It’s not the optimal solution, but as a workaround until v1.21.0 I’ve found that by disabling the Enable formatting (ktlint) rules option will allow for the rest of the rules to run as expected.

[cortinico]

As of now, this will most likely be fixed in Detekt 1.21.0
