Crashing faster

Just finally started playing during the past couple weeks, already can't do dungeons because Xbox series s crashes pretty consistently when trying to load them. Gotten to the point where I've gotten a decent amount of the legendary pals, but now when going to farm Blazamut or Beacon (really just moving about in the world) it crashes almost immediately after I get on my mount after fast travel. Thought it might be because Frostallion/Necromis might be too fast and the console can't handle it, but didn't know if anyone had some insight.

Also I can't place lyleen in my base without her bugging at the pal box. Not sure if it's because it's too short of a space but it's 2 wall heights tall. I can carry her to assign to a specific farm and she'll work, but if she's left to work on her own she teleports back to the palbox and bugs there. Considering making it one wall height taller but don't want to if I don't need to because the structure is very large.
