project not saving at all on premiere rush

Hi,

So, I was nearly done with a project and twice, a pop up came up to close application so it could save, it stated that it hadn't saved my work automatically for a while now. But this always happens at the end, and i closed the app several times in between adding scenes. So, is anyone else having this problem just before you're finished with a project and this pop up shows up, and you close the app and your project is lost? I know i saved my work, so not sure what the issue is. And yes, before anyone asks i did just update the software. Any help would be appreciated, thank you.
