TS3.6.4 Crashed on Launch-IOS12.5.7

Hey folks, I am using a very old device iphone 5s, my ios version is 12.5.7. I downloaded the latest version TS3.6.4 from Appstore,but I can’t enter the software. It just crashed on launch without any hints or notice on launch, is there any solution to this or it just doesn’t support the old device like mine? Thanks for help.
