### Issue description

Hi,

Found a rather annoying bug in 4.0 RC1 official on Windows 11:
When right clicking on a function in code and selecting "Lookup Symbol" - it does not always work?
Sometimes it works, sometimes it does not work?

Any ideas?

Jesse

### Steps to reproduce

Right click on a function in code and select "Lookup Symbol".
(it does not work always?)

### Minimal reproduction project

N.A.
