Plugin suddenly stopped working

I was using community Ocean Plugin in my project for a while. Suddenly, it started to throw weird errors about fail in asset finding ( The plugin is unchanged and stays at the same directory, where it used to be ) There were some movements of the ShipOfTheLine class though, but it does not seem to use the Plugin any way. ( At least the Blueprint editor shows nothing about this ) When I try to add a component ( It is present in the class list ) that is located in plugin to a blueprint, the editor either crashes ( about 50% of the time ) or just throws it away on restart, but it works before I exit the editor!

I tried rebuilding the plugin by deleting binary folders, but it did not help anyhow.

The more I explore - the worse it gets. I have taken my previous version of the code that used to work just fine. The first time I have tried to launch the project: everything was totally fine and worked as expected. After the second launch it started to spam the same message as you see on the original picture.
