arising problems when updating/installing Bonsai on Mac
Since a few weeks it began that updated Bonsai daily builds did not load in Blender 5.1.
While not having problems with 5.2 or 5.3.
Then I got the same 5.1 problem in 5.3 too, while 5.2 still ok. So for 5.3 I switched to BonsaiPR which worked.
Sometimes it loaded anyway after restarting Blender, sometimes not.
Anyway, meanwhile I reached a state where neither Bonsai daily nor PR will load on any Blender version :(
Could it be a problem that I have installed always both Bonsai versions, daily + PR ?
I do switch between these very seldom, but if, likely without restarting Blender, by deactivating the active, a bit of waiting and then activating the other version.
Do others experience similar problems installing Bonsai on Mac in general. Or switching between daily and PR in general ?
Usually I get a red error message (similar to restart hint after updating). Something like 2could not start/load Bonsai/more in Blender console)
In this case there are no usual entries in Blenders Scripting Tab.
And I do not find how to open Blender's console ....

BTW,
uninstalling all Bonsais, restarting Blender todays 5.2 Beta, installing Bonsai daily - doesn't help.
I get the same warning ....
