this program is used for packaged games is not meant to be run directly - Exe has old date

Very strange one here.
Today two workstations can’t seem to successfully build anything. We’ve tried existing projects, fresh projects just using the third person template, as well as two different engine versions 5.2 and 5.3

After the packages are built, the exe generated does not have the current timestamp. It has a timestamp from 1 year ago. When you try to run the exe it gives the error:

this program is used for packaged games is not meant to be run directly

Has anyone seen this before? It’s weird that it’s affecting two different workstations across two engine versions.

Edit: No idea what was actually wrong, but reinstalling Unreal 5.3 fixed it both for 5.3 and 5.2 suggesting something universal was corrupted. Weird that it happened on 2 machines.
