Corrupt Application Root File(s)

Hi there,

Recently I updated to Premiere 26.5.1. Upon opening it for the first time, the Finder informed me that there was something wrong with the file and the application could not be opened. The Finder suggested I move the application to the Bin.

I promptly reinstalled it, alas to the same message when I tried to open the fully reinstalled application.

I am currently reinstalling the latest LTS version; this major issue is thankfully not affecting my work and I am found once again grateful that Adobe has made every older version easily accessible.
