I’ve encountered the same problem. @sandermann is correct - deleting the Intermediate folder works, but the error occurs on the next build. Have you guys found a solution to this? I don’t want to be forced to delete the Intermediate folder after each build.
I figure, that this is happening because the file is named “-arm64_AndroidManifest.xml” instead of just “AndroidManifest.xml”, but I wasn’t able to find the part of code responsible for the name in the engine source.
