/insightscommand. The closest one is #43106, but it has already been closed. However, I still encounter this error when running the/insightscommand in the current v2.1.114 version.This issue still exists in version v2.1.116.
Reproducing on macOS as well.

Same behavior — command crashes immediately, no report generated.
