How do I Fix these import errors of my 3 year old C3 files? I've reviewed a few other topics on this

After I get "Failed to open project. Check it is a valid Construct 3 single-file (.c3p) project." I press f12 and review the console information. The console errors show "main.js:894 [Project] Exception opening: Error: name already in object class namespace"

I don't know where to go from there. This was a c3 file I haven't opened since early 2020, and I wanted to jump back in. I already have over 1k hours into this save and I really don't want to lose it. This is happening with EVERY file that is in my folder, including the backups. I even opened the files as zip, and tried open local project folder, and this isn't working either. I know the files all worked when I left them last.

Try opening in older versions and saving again.

A lot has changed since then, maybe using intermediate versions you will get to the current one.

I was able to open it using v185, thank you for showing me the downgraded versions page. I think it's because I have 3 Rex plugins installed, and when I opened the project in r234, it tells me that litetween support will be going away. So i'll try to rewrite my codes, or remove his plugins to see if that works.

It looks like one of my issues is that im using an old version of functions across all of my event sheets. Is there a way to convert old functions to the new way they work? If I have to delete all functions of my game, in order to open them in a newer version just to recreate them all, this will absolutely break my entire game.
