I got my first Pi Pico 2 and started trying things on it immediately. It loaded circuitpython just fine, but I realized that my project was going to require micropython instead. I reloaded the board into bootsel mode, and it came back up as a blank drive, as expected. When I drag the latest uf2 file from https://micropython.org/download/RPI_PICO/ the board un-mounts, but never re-mounts. If I disconnect and reconnect the board it still doesn't mount. Thonny seems to be detecting the board as being in "FS mode" but nothing seems to work from the Serial command line. I can reboot the board into bootsel mode to reset it, but none of the uf2 files I've tried are working. I'm on a Mac Mini running Sequoia 15.6.1, and using Thonny to interface with the board. Any help would be greatly appreciated!
