Urgent help needed I may have mistyped my pin number to prevent unauthorised sending of my bitcoin

Help is needed I have attached a photo of the app that I used I purchased some bitcoin quite a while ago and I set a spending pin I am pretty sure I used a specific code that only I know however unfortunately you only have to type the pin number in once and I believe I may have mistyped the code I intended to insert is there any way shape or form that I can retrieve my spending pin so I can send bitcoin without the pin my money is basically stuck within this app and I really don't know what to do

Surely to God the PIN number that I set and created is stored on my device or it is hidden within the backup file when I backed up my wallet and I must be able to retrieve it from my device somehow I really don't know what to do and I am lost please help

At this moment in time I just want to go into the kitchen slide down the refrigerator onto the floor having a full mental nervous breakdown and cry like a little bit on the kitchen floor in a puddle of my own piss I can't believe this has happened
