Cannot install 4.4.4 on Mac, OS 15.2

I've tried numerous times to install MuseScore 4.4.4 on my Mac, but I keep getting this error message:

"The operation can’t be completed because some items had to be skipped. For each item, choose File > Get Info, make sure “Locked” is deselected, and then check the Sharing & Permissions section. When you are sure the items are unlocked and not designated as Read Only or No Access, try again."

I've downloaded the installer several times, and each time I try to install I get the same message.
