ArduinoIDE really is just such total garbage. I must have fought for two hours to get a simple demo up on a TTGO board for my wife. Absolutely unreasonable, and in the end, I got it with PlatformIO. Now PIO has its own learning curve that I was interacting with while already at peak frustration, and the VS Code part of things makes me sad, but it does have this lovely property that if you fuck around with it awhile, it actually works eventually. ArdIDE on the other hand, I've never had a not-crap experience with it, but it does somehow feel like it's achieved worseness in the private equity years, or whatever kind of soul-selling it was, I don't keep up on that.
