Cache folder select error

Dear people, hope you can help me

I keep getting a notification that I need to select the cache folder select errorwhen starting popcorn time on my Xiaomi mi box
I have tested all versions and always get the same problem.
I have not yet tested the latest version of popcorntime, but it will be the same again.

does anyone have an idea how to proceed now ??

Can seem dumb but have you actually tried to change the cache folder in the settings?
