Issues with IOS downloads crashing when opened

Is there a new problem with downloading IOS apps for testing? I have been developing apps for the past few months and have been downloading them to IOS devices without issue. I do this as my apps use maps and I dont always get the response I need when I use the Thunkable LIve preview. However I downloaded an unchanged app yesterday that used to work and now find the app crashes as soon as it starts to load. I see a white screen and then that shuts down. The apps do work using the thunkable live IOS app but not as stand alone, downloaded apps. I have tested this with all the apps I have built recently and none of them now run natively. I cannot test on an android device as I dont own one.
Has there been a change in the build process? Can you advise as I am sure I am not alone in finding this more than a little problematic.
As an example try downloading this small project onto an IOS device.

i confirm this too

There are other reports of app crashes. See this:

I can confirm that downloaded iOS apps crash immediately. I don’t know about web apps. Quite frankly I’m not prepared to test it to find I have broken an app in production. As far as I can tell, apps tested in Thunkable live do still work. Thank heavens for small mercies!

Same here. Even an empty screen with only “Bottom Navigator” template used crashed when downloaded as iOS app for testing.

I confirm, it also happens to me
