At first I thought it was the SketchUcation plugin that was causing this, but after removing the plugin
I also noticed this problem and it is sometimes worse, he rectified a plugin that I did not rectify
I even have plugins that do not deactivate, even better, I have a plugin that indicates deactivation but it remains active and functional
I have a lot of weird things with SU2024 in addition to random crashes at startup, but when testing on the latest version of SU2023 I have similar behavior
I'm not at all an expert in ruby api sketchup but I have the impression that if the plugin is not correctly coded it can behave like an SU plugin, but probably not all the time!!!
