Using Sticky Mod on a rotary encoder on the Lulu makes the board unresponsive and unrecoverable without reflashing

[jtgamble]

Using a custom keycode on the Lulu that includes Sticky Mod (KC.SM) and applying the custom keycode to an encoder makes the Lulu completely unresponsive. The only resolution is reflashing the side of the board that you saved the keymap to. I haven't tested this with non-encoder keys.

Stub of the keycode I tested with:
"code": "KC.SM(KC.TAB, KC.LALT)"

Flashing never completes (OLED shows the py image) and the red LED on the back of the board flashes twice - short break - flashes twice. Unplugging / replugging in the board does not resolve, only reflashing recovers the board.

have you tested the keycode your self? Also if you can check your keymap to make sure peg is injecting the keycode correctly? Your board locking up is a problem but its happening because the keymap has a keycode that is not valid. If peg is butchering your keycode its a peg problem if the keycode does not work anyway its a kmk/keycode problem
