Duplication of entries in Source Files field when applying changes to yarnproject

[H3G0A]

Whenever I make any change to a .yarnproject file in the Unity inspector, new entries appear in the "Source Files" field. The entries are always the same: **/.yarn, and each time I repeat the process, more entries appear at once.
If I create a fresh yarnproject it will start fine, with only 1 entry that says **/.yarn and the first time I apply a change, 2 more of that same entry will apear. The next time, 6 will appear and each time that number doubles. This happens even if I delete all entries before applying changes.
Furthermore, nothing happens when I click the button to add new entries myself (although it lets me "apply changes").

This behaviour only happens on my computer, but it happens no mater what Unity project I'm on. It doesn't even stop even after reinstalling unity/unity hub from scratch and cleaning any leftover files.

This problem began happening after some time using yarn spinner, it didn't occur at first. However, I don't recall commiting any significant changes related to yarn spinner during that time.

• Yarn Spinner Version: 2.4.2
• Unity Version: 2022.3.30f1
