I can't update via the Update button. Force update causes Internal 500 Error.
I know, I've realized I'm insanely far behind on updates. Honestly, I never successfully updated before, and since it always said "Update Successful", I've just assumed that the page looks the way it should, and that it's normal to "list the change list" essentially. I noticed a buddy had some more features than me, and wondered why updating wasn't showing new features. After looking into a ton of posts here and going down a few rabbit holes, I've learned that "Update Successful" was actually cap. It very much never has been successful lol.

And here is my current PHP version:
PHP 8.3.6 (cli) (built: Mar 19 2025 10:08:38) (NTS)

Zend Engine v4.3.6, Copyright (c) Zend Technologies

Database is also fully up to date. I think.

Last successful update (Install date afaik, so maybe "last successful "update"" is the wrong phrasing):

I'm also not 100%, but I think I ended up on the "Develop" branch somehow. When I try to switch to master, it breaks as well.
