I recently downloaded MC commander for my sims 4 and before downloading my game would freeze and move slower. I soon noticed that last exception text were popping up in my game as soon as it booted up. Thinking it was a mod problem i downloaded mod conflict detector and got rid of the mods with issues. It booted up fine no error text, but then the files came back along with a few crashes. I took everything out my mods folder but, still no fix. I get the following same error sorry about the length but please help it looks like core game issue im not sure i can be fixed :

You need to send this to Deaderpool over on his Discord channel for MC Command Center support, but nine times out of ten he's going to tell you it's caused by outdated mods or custom content.

I got LastException Errors too, and I'm using MCCC mod only. But I hear that using 3.5.0 will fix the issue but I never tried it.

I'm no expert but it looks like you have a lot of mods that are outdated. Just from what I see.
