iPad 9th Gen lagging and crashing after iOS 26 update

I’ve been having issues with my 9th generation ipad lagging quite a bit and struggling often to load apps, despite still having 28 gb of storage left, especially while playing the only game I currently have on it and while opening discord and sometimes just when closing apps and opening the ipad to scroll to other apps. sometimes those apps will black out while im doing something in them as well or just be very slow loading or crashing because it struggles to load parts of apps, on average i crash about or under every 3-5 minutes while playing my 6 gb sized game. I’ve also tried just about everything I can find for stopping both the games lag and my ipads general lag, deleting apps photos and other stuff, turning off the liquid glass effect waiting updating and every time i try sometime the lag and issues get a bit better for maybe an hour then goes back to how it was. I’ve contacted the supports for both that app and from what I'm getting it seems to be a problem from my device from what research I’ve done it seems most other generation 9 ipads and even older have been doing fine with the new ios 26 update (my ipads on the 26.5 right now and quite unsure about updating it more since I noticed these issues only after the 26 update). Also the lag stays about the same no matter what battery percentage the ipad has (tho its almost unusable at anything under 10%).What else could I do? Is there sometimes else wrong or do all the older ipads have these issues after the new update?
