When we talk about a “freeze”, how long is this freeze? a second? more?
The technical bit is that it might be normal behavior. Many UI interactions seem not to be optimized as async operations, but happen in sync. When something happens in sync, a computer “waits” for a code task to finish before moving on, which can result in a freeze. When something happens async, you’d be able to do whatever you want with the UI while tasks run in the background. Other types of freezes (usually seconds or more) can indicate errors in the program, for which you can read the engine log at their timestamp. (\MyProject\Saved\Logs*******)
Your PC specs look fine on paper. Looking deeper into your hardware without more direct logs might lead to a large amount of possible guesses.
