Eclipse delete Plugins from Folder

Question

So I was using Eclipse 2022-06 Version and everything was working fine.

I then wanted to install JBoss Tools Plugins (Eclipse Marketplace) which also looked good. After the Installation Eclipse asked to restart, which I did.

Now my Eclipse cant be opened again. Its gets stuck on load screen and Java Runtime takes 100% CPU. Is there a way to delete the last Plugins that were installed? If yes then from what folders and how do I make sure to only delete that part?

I am trying to use the newest Version but my old setup had some packages and preferences that I dont want to lose..

Although it's not simple, the p2 Director application can handle it. It's Documentation (somewhat).

Another alternative is to try creating a brand-new workspace; occasionally, it's the workspace rather than the plug-in itself that causes an issue.

The only other choice is to just remove your Eclipse installation (but keep your workspace) and then re-extract a fresh copy. It's simple to perform because Eclipse's "installation" is simply a zip/tar extraction. All third-party plugins that you already have and want to keep would need to be re-installed.
