Yarns - Sometimes boots to bootloader?

Not sure if this is a problem with my power, but I’m definitely way below amperage.

Sometimes, every 5-10 boots or so, my Yarns will boot with the snake pattern/bootloader engaged, as if I booted it with the encoder pressed in. Any ideas?

Retail, newest firmware (v1.3), everything else works flawlessly.

Could it be a mechanical problem? The encoder getting stuck in the pressed position?
