It seems that MacOS desktop builds do not work properly on Macs with M1 chips and Big Sur OS. Being activated via Steam such builds crash, Steam also displays two errors: a system one that says that a user has no permission to open the app and Steam’s one with a text: OS error 4294956470. As I know that is not Solad2D’s unique issue, many other game engines have similar problems on M1 Macs.
