Looked and didn't see this reported elsewhere, but I am having problem with my external editor (TextMate2). I have always used it with Unity, but since the beta 2020.1.0b4, whenever I double click on a script in the inspector or an error in the console, or in the project panel, it opens a new instance TM2. Took me a while to notice that I had a dozen instances. I tried repointing in the prefs, but still the same. Works ok in a non-beta version. It's not a game stopper, but mildly annoying. Is there a fix/workaround locally?
