This happened to 3 Teensy LC's. They are all boards that I have used in other projects before. When I went to upload my sketch via platformIO on VS Code, it uploaded once, and when I went to upload a second time it says "No Teensy boards were found on any USB ports of your computer." I've also pulled up teensyduino, and it doesn't see the teensy either. I haven't worked on any arduino projects for a while, so there may have been some driver update or something since last it worked.
Board not detected by computer after first upload
