I also added ```def nav version = 2 3 0 alpha01 classpath androidx navigation navigation safe args gradle plugin $nav version ``` to classpath dependencies

You can either try cleaning your cache or find the file that isn t formatted properly

Geert · Answer

Yeah I already invalidated caches and restarted the project

Geert · Answer

The problem seems to be in xmlPullParser Cannot remind me that I ll use it

Geert · Answer

Already deleted the m2 maven folder but doesn t seem to help It only contained another dependency

Geert · Answer

Unfortunately it doesnt solve the problem < zhuinden>

wasyl · Answer

Don t you have any additional whitespace at the beginning of the file with navigation graphs xml

Allan Wang · Answer

it might be one of your resource files and not a generated one As mentioned is fine for gradle files

Geert · Answer

< Lucas Ł> im trying to find them but not in the navigation or layout folder

wasyl · Answer

The crash occurs in `parseNavigationFile` so it does seems like one of the files with nav graph is the culprit

Geert · Answer

Well the problem seems to be MacOS related <https stackoverflow com a 60035821 4713369>

Geert · Answer

There was a hidden DS Store file in the navigation folder

wasyl · Answer

Definitely worth reporting They probably shouldn t even try to parse non xml files
