Manga showing a grey screen after update about mangayomi

I have the same kind of error but with an error written :

Have you tried to do backup before update?

In my case, it takes an old backup regardless if I made a new one, so I have to delete all backups in order for the new one to take affect, but that's a different issue. I tried reinstalling the app and I was able to access the manga again with an old backup, but once I refresh the library, it went back to Grey and can no longer access it, and it's only a few manga that I'm having this problem with.
