Need help, JDT auto completion runtime exception [message #1861746]

Been using Eclipse2023-09 with Java17 a few weeks now when the auto complete feature decided to start giving this error as I was typing. I have not changed anything in Preferences>Java>Editor, or restarted Eclipse prior to this error. It was working one moment and didn't the next.
I have tried reinstalling from the launcher and the zip package into clean directories but that doesn't solve the problem. I am still able to run my project so I assume Java17 is working fine.

the attached files are a image of the error prompt and a copy of the last entry from <workspace>/.metadata/.log
index.php/fa/43666/0/

*edit: corrected version year typo from 2020 to 2023

edit: SOLVED
Auto complete throughout eclipse decided to work again after I made a new Java project and tried to edit code in the new project. Seems to have been something related to the original project that was causing the error?

Perhaps it's a good time to install 2023-09?

If the problem only occurs in the original project and only at a specific place, it could be a bug in JDT. In that case, you could try a development build from 2023-12 to see if the problem is fixed there. If it's not, you could report it to JDT.

If the problem occurs everywhere in the code in the original project, I suppose something else got broken. I don't know enough about JDT to judge what that could be.

Hi there! I'm having some issues with JDT auto completion, and I'm getting a runtime exception. I saw that the latest version of Eclipse is 2023-09, and I was wondering if that might help resolve my issues. Has anyone else had similar problems, and is upgrading to the latest version worth trying? Thanks in advance for any advice!
