This sounds similar to <http://issues.guix.gnu.org/44257>.  Do you 
have an ATI video card?  They are known for problematic hardware.

Please try the two work-arounds suggested there: adding ‘radeon’ 
to the GRUB kernel command line, or burning the ‘latest’ ISO if 
that doesn't help.

Kind regards,

T G-R
