I just tried again and still the same error “Failed compiling Android resources” with dmengine
On my main project the error message changed yet again
/defold-rive/plugins/lib/x86_64-win32/libRiveExt.dll
D:\Développement\Defold Engine - Projects\Project\build\plugins\defold-rive\plugins\lib\x86_64-win32\libRiveExt.dll (Le processus ne peut pas accéder au fichier car ce fichier est utilisé par un autre processus)
This is the message I literally got, it means “The process can’t access the file because the file is used by another process” hope it helps, might be a whole different problem.
