Possibly working Pimoroni builds of v1.22.1 (the bugfix release of v1.22.0) are available here: CI: Bump MicroPython to v1.22.1. by Gadgetoid · Pull Request #892 · pimoroni/pimoroni-pico · GitHub
I haven’t tried any of these yet - stuck in Raspberry Pi Python world - so any feedback is welcomed and appreciated.
WARNING: This build changes the LittleFS filesystem version, back up your Python files before updating!
