Connor,
Sorry that you are seeing this issue. Thank you for the log file.
It looks like the failures are from Eclipse plugins, might indicate a corrupted state. I ran few tests with temporary disabling of CodeMix on Eclipse 4.13 with Java 11 and could not replicate the issue at my end.
Can you please try starting Eclipse with -clean command args, switch to a new workspace and check if it loads fine?
Edit the eclipse.ini file located in your Eclipse install directory and insert -clean as the first line. Or edit the shortcut you use to start Eclipse and add -clean as the first argument. You can also run it from command line : eclipse.exe -clean
If the above does not help, then the quickest way to get back on track is to get a fresh copy of Eclipse. I have filed the errors for further investigation with the dev team.
Apologies for inconvenience caused. Please let us know how you get on with this issue.
