By the way: This is not what caused you the problems (the use of PaperUI)
The root-cause of your issues is the following: the offline addons .kar file (which comes with Choco) has a problem and when it is copied to the userdata/addons subfolder, OH2 starts to install every single available Add-on (actions, bindings, transformations, persistence, etc, etc). Of course, since none of these Add-ons are configured… logs explode
This has been already fixed in the latest Milestone Release (2.4.0.M6)
Also, as a second step, the Choco installation method is beening updated not to include the Offline Addons package anymore. Users can now use PaperUI to install the addons that they really want.
