32-bit Linux Distro Recommendation

I try to install Deepin 20 on an old Dell Dimension 4600 today. And I get a message "unable to boot - please use a kernel appropriate for you CPU". After some thought, I recognize that I tried to install a 64-bit OS on 32-bit hardware. The previous version Deepin 5.11 doesn't seem to have a 32bit version.

Can someone recommend a 32bit Linux distro?
