App crashes when decompiled with resources

[filip-769]

I am trying to edit the network_security_config.xml file of an app (com.telekom.magiogo) to allow me to mitm-proxy its traffic without root.
The app works when i decompile (then build, sign and install all parts) the base apk inside the xapk with the -r flag.
But when i try it without the flag i get this error when trying to launch the app:

I don't really understand why this is happening because i haven't modified any files.

The simplest way is to use some other tool to merge your split apks into a single apk file, then decompile, build.

Merging the apks into a single file worked. Thank you!
