Jassert with Android App build on Windows 10 / RuntimePermissions Problem


i encountered a problem with running an App for Android build on Windows 10:
if i want to open a file i get a jassert that i did not granted permission, but i did granted permission. Also Android Studio cannot find many of the class references in “juce_android_RuntimePermissions.cpp”, but i get no compiler errors.
I think it is a Windows 10 problem, because when i create the Project on Linux i have no problem. This is also true for the demo projects.

Am I missing something?
I’m using:

Projucer 5.4.7
Android Studio 3.6.1 (Target API: 29)
Windows 10

Thank you all in advance,
