any hint?

can provide demo project (yours if possible) reproduces issue? we'd take look.

as workaround: if not have custom native code in android\native folder, delete native folder , import 6.0.0.x project 6.2.0.0. should work.

for might have custom code: can mirror file construction of native folder in nativeresources folder below it. way - after upgrade, , during build time - custom code auto-copied nativeresoucres folder native folder.
