Help/Support apps loading but not opening

[Lisa G 2 iPhone 15 Pro Max 18.2]

Hello. I only messaged you here so that I’m not posting another sites name for everyone e to see . I paid for Singulous & on the Singulous app I can get my games downloaded but when I open them they get stuck matter u get the Iosgods menu & everything. In Iosgods when I download them I get iOS could big download integrity could not be verified. I did notice I the iosgodssigning certificate expired  &  it won’t let me delete the app. I’m sorry I know I’m not supposed to message you about this  but I’ve been trying since August to get 2 apps & I can’t through either app. I tried getting developer earlier & thru want me to pay it doesn’t give a fee option . I do not know a thing  about IPSA files. & cannot get sidelined with no of, Mac or laptop. I don’t own any.  At a loss as to what to do. I apologize I’m just frustrated. Singulous can’t help their app is working give it a big & I need to have the creator fix it
