Thanks for the quick reply, I have tried all solutions on there but it didn't work. I didn't have this trouble with the previous versions.
On M1 macs:
• right click FakeFamilyV054.app.zip -> Open with -> Archive Utility
• right click Fake Family.app -> Get Info -> click 'Open with Rosetta'
• open Terminal, enter 'xattr -rc /Path/to/Fake\ Family.app'
edit: on newer versions of macOS you have to use 'sudo xattr -rc /Path/to/Fake\ Family.app', enter password when prompted
• right click Fake Family.app -> Open , choose Cancel
• right click Fake Family.app -> Open , choose Open
Hope this helps.
