It seems clear that ColdCard Mk3 hardware wallets with firmware version 4.0.1 and ALL later firmware versions of the Mk3 are compromised.

It is advisable to CALMLY and CAREFULLY move your bitcoin to another wallet address that was NOT generated by a Mk3.

If you have a Mk3 with and earlier firmware version it is still advisable to move your funds to a fresh wallet generated by dice rolls etc.
