Adobe Rush refuses to render no matter what I try!

Anyone from Adobe, please help! I use Adobe Rush on my iPad Pro 2022. It has been buggy from day 1. I regularly have problems with my projects not exporting. My latest one refuses also to export. Usually I manage to find a workaround by doing some random arbitrary thing from turning my device off and on, to resetting all my settings, to uninstalling and reinstalling the app. I try duplicating the project, I try different settings for exporting, I try removing certain graphics and transitions. This is beyond intolerable and Adobe needs to get their act together. Can someone please tell me how to get my video out so I can upload it and not have to do the whole thing again (which takes several hours) with different software that I'm not used to?

There is no one error code. Sometimes it just says unable to render, at various points in the process. Other times it just throws me out of the app. Once it reached 99% and told me it couldn't save to my camera roll. It has also told me I don't have enough space, which is also wrong - I have ample storage space, both on the device and in the cloud.

Also I have tried exporting on my laptop, but it doesn't work there either.
