Crashing and loss of progress on premiere rush on ipad

Hello, I was working on a project in premiere rush today on my iPad Pro and I switched to another tab and when I switched back the app abruptly restarted and when I reopened it I had lost about five hours of work. I had been switching to other windows and tabs throughout the project and there had been no issue I checked my cloud files and there was no option to recover the lost version. This is incredibly frustrating. is there any way I can recover these files?
