Premiere Pro Install Failure - Disk Image Couldn't Be Opened

Hello!

 recently purchased a MacBook Air (M5) and tried to download Premiere Pro and the Adobe creative cloud. However I keep getting an error message saying "The disk image couldn't be opened - The disk image is corrupted". I've tried redownloading the dmg files, restarting my laptop, using coding to try bypass security to install the files but nothing has worked.

Some YouTube I’ve watched regarding this issue (no success)
