This looks like you may have upgraded modules from the marketplace without cleaning your userlib first. This means you have different versions of the same jar files causing a conflict.
To fix this, you can manually go into your application’s userlib folder and look for .jar files with the same name, but different versions. Delete the version(s) with the lowest number, but the same name.
There is a tool on GitHub that can help with this if you don't want to do this manually.
Alternatively, in your App’s Settings → Deployment menu, you can unselect the duplicated .jar files.
