Visual Studio Code – VS Code Intellisense loading forever in typescript project

Problem

It keeps being stuck in Loading when I hover on a variable/method/import.
Normally you can ctrl + click to see the reference on the entity.

Background info

• Using VS Code version 1.95.2 for a typescript project
• Other ts projects don’t have the issue
• This project is fairly large, but other people don’t have this problem on VS Code
• It had been working fine a few days ago for me, only me making very minor code changes
• Manually updated VS Code from 1.8x to 1.95.2 a few days ago

Attempts tried:

• Restart VS Code alone –> does not work
• Reboot PC –> works temporarily (stops working after an hour or so)
• Switch Intellisense typescript version from vs code version to workspace version –> works temporarily after restarting VS Code alone
• Switch Intellisense typescript version to use the nightly ts version as seen in this git issue –> works temporarily after restarting VS Code alone
• Clean reinstall of the same version 1.95.2 –> does not work
• Should be unrelated: npm install again after deleting node_modules and package-lock.json –> does not work

Thinking of now experimenting with clean installing to the older version I had. Or migrating to use other IDEs.

Edit: I find that if I disable the github copilot extension, Intellisense works fine again.
