Update 2: Again fast charging not working. And the method I mentioned below is not working now.
Update: I solved my problem. First I connected a fast charger to my device, then went to settings> diagnosis, then diagnosed the charging option. Nothing happened. Then I put my phone to a wireless charger, enabled the fast charging for wireless, then diagnosed again for wireless charging. After that, I again connected my phone to a fast charger and diagnosed the Charging option again. And that fixed my problem.
My s24 ultra stopped fast charging after the July security update.
