Lost Fresco File After Being Asked To Sign In While Exporting It

I created an artwork in Adobe Fresco on my iPhone while signed out. When I tried to export it, Fresco prompted me to sign in. Immediately after signing in, the artwork disappeared from the canvas and is no longer in my gallery. I did not uninstall the app, switch devices, or clear any data. Is there any way to recover the local document or access diagnostic logs? Please answer ASAP I worked on this for 3 hours didn’t know I had to sign in…
