Unable to load library list

[problemss]

I just installed ExportTools on my NVIDIA Shield via UAS. When I select the load library option I receive the following error and no libraries load.

2019-12-09 21:26:23,796 (2bccfbd4f0) :  CRITICAL (sandbox:303) - Exception when calling function 'ValidatePrefs' (most recent call last):

My files are in an editable location. I can some other changes to the settings and they save fine.

Just to add, I did try the manual reset mentioned on another issue and it didn't help.

No idea if Shield works with ET plugin here, but note that the user running PMS, must have write access to the plugin directory

Also, a small snip from the log is not 100% helpful. Better with a zip file with all the ET logs

Yes I can write to it. I'll grab more logs.
