Issue java.util.Iterator java.util.List.iterator()

[DasJ0nas]

I got an issue on my Pixel 6 Pro where whenever I try to use anything in grocy it just throws me an error.

Issue still remains after deleting app Cache and Data and reinstalling the app. I tried to resetup the server config on my device and tried a different API code however the error still persists.
On my iPhone the grocy server and API keys work flawlessly so it must be a Problem with either my device or the app.

Error code:

Error: Attempt to invoke interface method 'java.util.Iterator java.util.List.iterator()' on a null object reference

java.lang.NullPointerException: Attempt to invoke interface method 'java.util.Iterator java.util.List.iterator()' on a null object reference
