i'm working on updating a compiler plugin to use kotlin 2.2 and i'm getting the following error: Exception during IR lowering with a stacktrace that starts out

i'm sure the problem is in my plugin, but the error doesn't give me any information about what code actually caused the problem. any suggestions on chasing down where the actual problem is?
