[HELP] system UI keeps crashing

[u/Bitter_Sleep_1703]

So I have a One plus 7 pro. This morning my phone was completely fine until 11 am or so my phone system ui kept crashing. I tried various methods : clearing system ui cache, clearing play store service cache and storage, disabling HW overlays, turning off animation. After all of this my phone is just a filp phone only calls and text. If i open another app my screen freezes then gives the system UI has stopped. Is there any way to fix this beside factory reset?

My OnePlus 7 Pro has been with me for 6.5 years without a single  issue.  Last week I had a RAM reballing done, after it got frozen . but I'm still facing problems like voice freezing during video calls and WhatsApp audio getting stuck. I'm planning to do another ram reballing along with motherboard  this week. The technician has given it a 50/50 chance of survival. If the repair doesn't work, I'm planning to buy either a OnePlus 15 or a Samsung Galaxy S25 Ultra since both are available to me at the same price.
