JabRef used to work fine, but suddenly it stopped opening on my Windows 10 computer. It is visible in my task manager, but for the rest it does not open. I am not entirely sure what I did last time before it stopped opening that might have caused the problem: upgraded to 3.8.2, updated Java, or both. In any case, I tried re-installing JabRef 3.8.2, installing 3.7 instead, and re-installing Java. All with the same result. Any suggestions as to what might be the problem or what else I could try to identify it?
