Cursor Disappearing?

Hello! I am not sure whether the issue comes from me or IDX, but when I load into an environment, everything works as expected. As soon as the TSX extension loads, or when npm run dev is executed, the cursor just disappears. None of the menus work anymore, code cannot be edited, the console cannot be edited either. It’s like there’s an auto-clicker somewhere on the page? Has anyone experienced a similar issue? It started doing this today for me. I have added a video if that helps.
Restarting the VM, refreshing the page and hard refreshing the page does nothing, the issue always come back.
Let me know what you think! I’m pretty new to programming, so it might totally be my bad.

Edit: the problem only occurs when npm run dev is running.
Edit 2: I disabled all browser extensions and the problem still persists.
Edit 3: The problem persists in other navigators too (Chrome, MS Edge)
Last edit: the issue is coming from IDX. The issue is not happening locally on VS Code
