There must be a better place to report this, but here you go: VS 2019 occasionally (meaning, several times a day) pauses for 30-120 seconds, typically when performing an operation such as "rename" for a variable or starting a build. The rename may be for a variable that's local to a function, so it's not like it's off searching the world for the impact of the requested action. It's almost like it's trying to access a network-remote resource on the UI thread.

I have no idea why it freezes -- you get a nice whirling disk cursor, and the UI is totally frozen. Windows reports the process as not responding. After a bit, the operation completes successfully, and you can go on your way. Things will be great for a few hours, then it'll randomly do it again. Not an earth-shaking problem, but annoying.
