When I delete a global folder that has items in it, the app crashes. Upon relaunching, the folder and its contents remain unchanged. In order to delete a folder without crashing, I found that I first had to delete its contents. I have also been informed that this occurs on other devices, which leads me to believe that this is not just a Xiaomi/MIUI issue.
Device: Xiaomi Redmi 9T
MIUI Version: Global 12.0.11
Android Version: 10
KLWP Version: Latest (v3.56)
I'm getting the same thing on a Galaxy S9+ running 3.56 on Android 10. Seems to only be nested folders though. Deleting the child folder first and then deleting the parent doesn't crash.
Also present on my Sony Xperia 1 IV with A13 and the latest KLWP Play beta 3.76b418415. Suggested workaround is working
I can reproduce this. It looks like you need to have at least 2 items in the folder for this to happen. Already reported to @frank.
