NitroPad boot issue

Having successfully booted my new NitroPad laptop computer with NitroKey Pro yesterday, running and updating QubesOS, today I get the following boot error:

*** Found verified kexec boot params
gpg:  verify signatures failed:  Unknown system error
Invalid signature on kexec boot params
!!!!! Failed default boot
New value of PCR[4]:  string of hex
!!!!! Starting recovery shell
/boot #

Could someone please help me with this problem?
