DataGrip 2020.1.4 was using a lot of memory ( > 4GB). After searching the common conclusion was that there must be some plugin that are leaking memory.
I went ahead and disabled some plugins based on the results of the profiler in the help section. I must have disabled the wrong ones, because DataGrip wouldn't start anymore. It asked me to completely re-install, which I did by redownloading it (using OSX), however that didn't solve the problem.
I have lots of open consoles that I don't want to lose, any help to make this start up again would be appreciated.
