When playing on my friends realm,everyones packs work normal but with me,everytime i download and activate a pack,ill use it for a while and week and then it randomly stops loading for me. The realm will either use the default texture or try mixing mine together with the default resulting in a lot of glitching textures and other issues. The only fix ive found was completing switching to a new pack over and over. Ive tried uninstalling and reinstalling minecract and the packs but that doesnt resolve it. Two examples of pack that have done this so far for me are clarity and blockpixel.
