Failed to load development version error message in Lightroom Mobile images (Android)

Hello, this morning I have discovered that all the photos, except the one I imported on Lightroom last night, cannot be accessed in my Lightroom app. They've been showing as this grey squares, and whenever I try to click on them it says "Failed to load development version". But its stated that it still have 413 photos (the ones now missing). I tried to sign out and sign in multiple times, even restarted my phone, but nothing works. 

Even on my phone Gallery, Google Photos, and Recycle Bin, everything from I exported from Adobe Lightroom is gone.
