Moved my game to an external drive and now I need some help

I followed this tutorial - https://www.youtube.com/watch?v=IYX--bbaLvs&ab_channel=Grace%7CSimmer - and moved my game and EA app/folder onto my hard drive and set up the symbolic link and everything. It took some trial and error, but I figured things out and moved everything properly, so now my game and the EA app, and its folder are on my hard drive, and my mods/cc/saves appear in my game.

But I feel like I'm playing a terrible game of whack-a-mole, where I solve one problem and another pops up. My game takes forever to load now that it's on my hard drive compared to when it was just on my Mac, and when the game does load, I can't click anything. I can't save and exit either, so I keep having to force quit the game. I updated whatever was cleared, but that didn't seem to help much, so I even deleted the majority of my script mods. Right now, I mostly have just CC installed, but I feel like something is broken anyway and messing with my game. I want to report what's going on to the BE Discord so I can get help, but the support channel is closed rn, so I'm waiting until it reopens or if someone here can help me. I'll attach a screenshot of the exception alert I got if that can be any help because I don't understand it or what I need to do to improve my situation. 

If anyone can help me, it would be very much appreciated. I just want to run my game as normal.
