Astah stopped working after upgrading ubuntu


Hello, so as the title says I had astah working just fine, but I upgraded ubuntu to the newest version (18.04) and now It doesnt work anymore, I already tried to remove astah completely through synaptic and installing again but nothing changed

I can't do anything basically.If i try to open a existing file or create a new one nothing happens for a long time, but after a while i get this message "An exception has occurred. Please restart Astah"

Here is the 2 logs
