im using pix light/dark material you icons

sooo yesterday updated my phone to one ui 8.5 and everything was ok it looked amazing but the second i open an app i get this horrible lag that wasn't there before, it has been turned off and on, cleared ram it doesn't have full storage etc and it really freaks me out cuz in one ui 8 was really smooth so idk what happened is there any way to fix it? the rest of the system is smooth tho only the laggy open/close app
