error: Couldn't load -exportOptionsPlist: The file “export.plist” couldn’t be opened because there is no such file.

Anyone knows why? I'm new to MacOS and I'm trying to figure out.
I'm on Monterey 12.2.1, xcode 13.2.1, macbook air m1

But if you want you can download this archive and this works

Like many non-Apple-signed apps, I had to right-click and select Open and then click Open on the popup before it would run normally.

@reukiodo This happens only the first time you open the app, right?
