Mobile app crashes when I enter P/word

I have not been on my NEM Wallet for ages. I have the app on my iPhone 11. I tried to log in and the app just crashes every time I enter my password.
I have no other way of accessing my NEM Holding. Please advise what i need to do?

Did you maybe from time of last login restored app/phone from icloud/itunes backup?

No I think I might have updated everything from my previous phone

So when you switched between phones I expect you used Apple backup?
Maybe this is the reason → New device iPhone - #6 by thomasoehri?
Have you private key backup?

Er… somewhere I think!
