Do you know how to fix this photoshop error?

Hey there,

So I wanted to continue a project and it get “some groups were found corrupted and repaired.” I click ok and then get “could not complete your request because the file is not compatible with this version of photoshop” Really, doesn’t make any sense since I used the same version as now, so what can this be ? I look for a fix on the net but cannot find anything that helps, so I’m asking maybe some of you got this. I don’t really want to lose a day of work for this nonsense but I guess I will, don’t I ?
