Hello

Is there a way to revert to a previous plugin version?

This is not officially supported. You’re better off working with the resource author to fix the issue honestly. 

There is no way in which to do this. You would need to contact the developer if you wish to do this, who may well be able to offer you a custom version. However if you have installed from the marketplace it would involve uninstalling to do this. In most cases though, it would be undesirable to downgrade something to an earlier release.
