NitroKey 3A Mini suddenly giving red LED, no longer recognized

Hey there,

I’m using the 3A mini for quite some time. When adding a webauthn registration, the key started blinking and I tried to unplug/replug. When registering again, the LED went to red and never changes. Using the button doesn’t do anything, dmesg or gpg --card-status or nitropy nk3 test no longer recognize the device. Plugging it in any pc always yields the red light…

Did it get bricked? I’m using webauthn for a long time, it never did this so suddenly
