I am trying to run a Xamarin.IOS app through visual studio community on macos but encounter the following exception on the splash screen, both in simulator and on a physical device. It previously worked, but after pushing changes (which worked) and taking a coffee break, the next time I built it stopped working. There is no VCS diff to the main repository, which runs fine for coworkers.
Objective-C exception thrown. Name: NSInvalidArgumentException Reason: Could not find a storyboard named 'Main' in bundle NSBundle </Users/User/Library/Developer/CoreSimulator/Devices/3AD1FBAC-EA67-4CC0-8D8D-212DA5429B51/data/Containers/Bundle/Application/7D30F8AC-D3A4-46FA-AA22-8EA50F1ABA43/Test.app> (loaded)

33 ??? 0x0000000187cb6963 0x0 + 6573222243I've been searching around and have found a few potential solutions to this issue, none have worked. I've tried:
https://stackoverflow.com/a/8776005/2751571 - In my case the storyboard is named 'Main'. This is consistent in the relevant locations
https://stackoverflow.com/a/37502912/2751571 - The target membership box is checked. I have tried unchecking this, returning to visual studio, and rechecking it.
https://stackoverflow.com/a/11547232/2751571 - Tried these steps, no avail.
https://stackoverflow.com/a/19240408/2751571 - Resulted in a black screen (though it did not crash after removing the row from
info.plist)
Note that a clean + rebuild was done for each of these steps. I've additionally verified that Main.storyboard is in the 'Copy Bundle Resources' build phase, cloned my repository into a separate directory, fully re-installed visual studio (along with downloaded frameworks), and a number of other things I've came across searching around. No luck.
It is worth noting that the default Xamarin.IOS project does run on my machine, but does not explain why this project only fails to run on mine, but works on others.
