Eclipse will not start and I haven't changed anything

Question

I haven't updated anything for at least a month. I was just working normally and suddenly the menus were all blank, so I decided to restart eclipse. I clicked "close" and "ok" to save everything, but nothing happened, so I clicked close again and eclipse closed. I clicked on eclipse and the loading screen only flashes and disappears followed by a message telling me to check the .log file. I've since restarted the pc multiple times, tried running it in safe mode and ran eclipse.exe -clean and nothing works.

Any ideas?
