I know you've probably moved on, but incase youre still looking for a solution, it is 100% a windows permissions problem. I can help you if you like, it's fairly straightforward.

All of these steps are performed within the (File > Right click > Properties > Security tab)

1. Edit > Add > Object name: "Users" (no quotes) > OK > Tick allow for "Full Control" > Apply > OK

2. Advanced > Owner > Change > "Users" (no quotes) > Tick 'Replace owner on subcontainers & objects' > Apply > OK

3. Advanced > Add > Select principal > "Users" (no quotes)" > Apply > OK > Full control > Add files & subdirectories > Allow > OK

Presto! Now, all files in said folder will have complete write & read access.

I came across this solution whilst trying to figure out how to display xmp-dc metadata (photo & video tags) within File explorer.

NOTE: If the file/folder already has tons of duplicate Principal entries (under Security > Advanced) - it will help to get a "fresh start" by pressing 'Disable inheritances' on each Principal, and then finally ticking 'Replace all child objects permissions with ...' > OK. (I forget, but I THINK you may need to re-grant yourself Full permissions real quick after replacing all child permissions)

Hey! Really appreciate your effort highlighting this. Yeah, that fixes the root of the problem. The issue, however, was created when I noticed that app crashed, instead of (at least) ignoring the problem.

I did not quite move on, but working on something else, so I just left issues unresolved, so that people can show interest in resolving specific problems within the app. If enough people bring the problem up, I'll spend more time resolving it.
