Android Question [SOLVED] Error while compiling (B4A 8.0)

[eurojam]

I have an older B4A programm which runs under B4A 7.3 but now I'll get the following error while compiling the programm with B4A 8.0. Then I rolled back to B4A 7.3 but the error is still there...at the moment I don't have any idea what to do?? Any help will be appreciated:

It is not related to the B4A version. This error can happen if you store the project on a network folder or some other restricted folder.
