Hello, I'm having problems with the xr management package. The XR Plug-In Management window is always disabled and won't enable anymore (saying "Installing packages..." even immediately after having installed the plugin management package 3.2.13 in a new empty project) When debugging I see "isInstallingPackages" being true so looks like somehow EditorPrefs "XRMGT Installing XR Package." exists. The issue first appeared when testing with multiple custom XR-Plugins. It worked fine when having one plugin enabled but sometime during enabling a second plugin the UI became disabled and never re-enabled. I originally used 2019.4.4f1 but tried new empty projects using 2019.4.5f1 and now 2019.4.1f1 and the UI appears disabled as soon as I install XR Plugin Management.
