My Friend can’t load into the Realm and I also can’t uninstall add-ons

Two separate issues, possibly related. We’ve been running a 7k+ day realm, total size of about 1.1Gb with these add-ons; actions and stuff 1.9, naturalist 3.2, waystones, Furniture Builder 2.0, and markers pack. If anyone else is having issues either with removing any or all of these or loading into a friends realm or world and has any tips to fixing it. I just hope my save isn’t corrupted. Its been a hot minute since I downloaded a copy. Thx in advance for any and all tips and/or help. ❤️🐦‍🔥
