Eclipse freezes while showing hover suggestions like method suggestions in class, method info etc

When I enter a dot operator after entering the class name, Eclipse will show method suggestions auto complete, at that time Eclipse hangs and gets closed automatically.
It also happens when showing method info. Can someone help with this?
When I checked Eclipse log, I saw these exceptions

Thanks #greg-449 for your comment.
The errors say that you have installed a plug-in which requires at
least Java 11 but you are using Java 8 on Eclipse 2019-09 (4.13) which
is now 3 years and 10 releases old. Try running on the current Eclipse
2022-03 (4.23).
It resolved after uninstalling the plugin which requires at least Java 11

You are using a version of Java that is too old. You should be using at least Java 8.

Hi from the logs i can see you are using JDK 1.7 which is not supported by Eclipse Neon or Oxygen.
Either Use Eclipse Mars which supports 1.7 or update to 1.8.

Eclipse not opening; "Unresolved Requirement"

As per this thread the answer is:
I took the first class reporting the error,
i.e. org.eclipse.osgi
and deleted the (lock) files under under configuration/org.eclipse.osgi/.manager
Files had names starting with .fileTable
I was then able to start Eclipse without a computer reboot but did have to specify the workspace when it restarted.
Just try this solution and It will work.
