Hi guys. I've been using a Teensy LC with my board for about 6 months and it's worked great until I started flashing code using Platform IO & Visual Studio Code. While using VSCode & Platform IO, my build times got significantly longer (up to 3 minutes to flash a small program) and often times the board would go unresponsive and I'd have to restart and press the 'reset' button. I just went back to the Teensyduino IDE and flashed an older iteration of my software that I know works, but USBMidi is no longer working...sort of...I can detect incoming sysex messages, but can't send messages out or detect anything on my input pins. What the heck happened?
