• Java version: Bundled JRE

Describe the problem you’re observing:

DBeaver won’t open at all, though the splashscreen does show.

I ran it with DBeaver CLI, but I can see the same error in ~/.debeaver4/.metadata

Fixed by deleting %HOMEPATH%/.dbeaver/.metadata/.plugins/org.eclipse.core.resources as specified in https://dbeaver.io/forum/viewtopic.php?f=2&t=1662. There wasn’t any .snap file. It’s a little annoying to lose the script associations but I guess it’s Eclipse’s fault and not DBeaver’s.

I had the same issue and this fixed it: https://github.com/dbeaver/dbeaver/issues/5517#issuecomment-473872921. Just wanted to add that for me that folder was instead at: %HOMEPATH%\AppData\Roaming\DBeaverData\workspace6\.metadata\.plugins. Not sure if that should have been obvious but I spent some time searching for it…
