@Arduino gave the usual recommendation (thanks!) which sometimes works, or sometimes the issue moves to a different version. I don’t think anyone has found a great repair. If desperate, do a Recreate, although on current Beta versions there’s a bug that can make it very slow. Both issues are now “fixed” however they need to be released for those on Beta. It’s being worked on but there are snags to settle.
If you’re willing to run Canary (you can’t get back to past Beta easily, but can go to next when it arrives), then Release: 2.0.4.34 (canary) 2019-11-05 seems pretty solid, except for some Stop and Linux issues. Canary releases are test vehicles, so they get the new features, fixes, and inadvertent breakages first…
