"Trigger Suggest" and "Quick Fix..." commands, code navigation not responding

Environment:

• VS Code Version: 1.65.x (also tested in 1.64.2)
• Extension Version: 0.22.1 (vscode-java 1.4.0, also tested with 1.3.0)
• JDK Type & Version: Amazon Corretto JDK 11.0.11.9.1
• OS Type & Version: Windows

Step to Reproduce:
Unknown, seemingly random.

However, restarting VS Code does seem to reset the issue but only temporarily, and the amount of time before the issue resurfaces varies, sometimes as short as a couple minutes, other times it lasts quite a while (hours, days).

Expected Behavior:

• Triggering commands "Trigger Suggest" and "Quick Fix..." (i.e. Ctrl+Space, Alt+Enter) should consistently cause intellisense popup to be populated with suggestions/fixes
• All code navigation (Ctrl+click, etc.)/"Go to ___"/"Find all references" commands should work
• Tests can be executed

Actual Behavior:

• Triggering mentioned commands manually using keybindings causes intellisense popup to appear, but says "Loading..." indefinitely. The following two entries are added to the LS log upon the Ctrl+Space ("Trigger Suggest") command:

  !ENTRY org.eclipse.jdt.ls.core 1 0 2022-03-28 10:08:00.387

  !ENTRY com.microsoft.jdtls.intellicode.core 1 0 2022-03-28 10:08:00.401
  !MESSAGE Completion request completed
  

  • Upon certain context-sensitive keystrokes, such as . (period after a reference, to access a member) and @ to add an annotation, suggestions do populate as expected. The following log entries are added upon typing . (period) after a reference:

    [looks like only the first five entries are relevant, but figured I'd include all just in case]

  • Other keystrokes, such as letters, which would normally suggest identifiers/members/imports/templates/etc. don't even trigger the "Loading..." popup.

• Some code navigation, "Go to ___" and "Find all ___" commands not responding
  • Not working: "Go to Definition", "Go to References", "Find All References"
  • Working: "Go to Implementation", "Go to Super Implementation", "Go to Type Definition", "Find All Implementations"
  • For those not working:
    • the loading bar beneath tabs appears and moves indefinitely
    • tried triggering using Ctrl+click, keystrokes and context menu commands
• A couple times these have resulted in significant, sustained CPU usage
• vscode-java-test plugin appears to have crashed (not sure if this is related)
  • extension is greyed-out in the extension list, cannot be enabled/disabled
  • no "Run" icon beside test cases in code editor
  • test panel not populated
