I have a Linux desktop using Debian Bullseye.

...

Any suggestions please as to how to solve the above problem ?

Are you running the stock 5.10.0-46 Bullseye kernel? Various newer kernels are no
longer supporting the NVidia drivers Kepler GPUs require, at least, not without extra effort.

If and when you find yourself unable to install NVidia's drivers, thus needing to
fall back to the FOSS drivers, yours should look just like mine (I don't try to use anything but FOSS):
