[Flutter] XCode/Flutter: How do I fix "ExportOptions.plist" is invalid error when trying to...

My app is written in Flutter, and I have been Ad Hoc distributing it to my Iphone multiple times now for sake of testing. To do this, I open my Flutter project in Xcode, Archive it, select distribute, then export, then install. This has successfully worked at least 20 times, as I have been doing a lot of testing. Like normal, I made some changes to my code - I was fixing the UI graph output - and went to distribute to my phone as usual when I got the error "ExportOptions.plist" is invalid.

After some googling, I ran updates on flutter dependencies and deleted the ios folder and generated a new one. The code still runs on a simulated Iphone no problem. It will also run on my Iphone while plugged in to my mac. However, I need it to run while not plugged in, hence the Ad Hoc distribution. I have seen people give examples of their exportOptions.plist, but I don't even know where to find it. I can't seem to access it in Flutter and I don't know where to locate it in Xcode.

Where specifically is ExportOptions.plist and how do I make mine "valid" again?

Update: I have located ExportOptions.plist. I will provide a screenshot. However, I am not sure what about it is causing the file to be invalid. How do I make the exportOptions valid again?
