Help/Support Sideloaded (unsigned?) apps won't open, even with AppSync

[ChristOurLife 4 iPhone 6 12.4]

Whenever I try to launch any Apple ID signed OR Ad-Hoc signed app (using Sideloadly), the app shows the splash screen and immediately crashes. I've tried:
Disabling and reanabling AppSync

Jailbreaking (with Cydia) and unjailbreaking (restarting)

Factory Resetting
Restarting (once more)
IOSGods App (app license removed)

Is there a known fix for this? (iOS 12.5.6, iPhone 6)

If you are jailbroken why not just use the deb cheat version?

Does something like IPA Installer help perhaps?

iOS 12 is quite old, make sure the app you're installing supports it.

Deb cheat version never worked for me. It does launch inside the app, it does have me sign in, but it just puts the watermark on the screen. Can't "buy" premium, it isn't unlocked...

Wdym just put the watermark on screen? After login with iosgods you need to turn the option on inside the menu for the cheat to apply

After you press thank you button and login there will be iosgods logo (face). Tap on it to open and turn the cheat option on

Thank you so much! I totally didn't know that you had to activate it beforehand
