I've had something break for me in VS2022 a couple of months ago that's really annoying, and I thought "VS2022 must be broken" and tried some things (like updating it) to no avail. Now got a new laptop recently and the same issue persists, so it must be with some setting tied to my account which I can't figure out for the life of me.
Basically my Intellisense is broken. If I do "classInstance." nothing pops up (I have to do ctrl+space manually), and then when the method has overloads, there's no way I can see the overloads, I end up having to shift+f12 to see the class members and figure out the overload that way.
Fixed via Tools > Import and export settings > Reset all settings.
