Dragonfly is built with --march=core2 but I guess even newer celerons lack instructions that are present in core2.
Unfortunately, I can not say which instruction is missing. If you wish, try to run the binary with debug symbols via gdb:
https://github.com/dragonflydb/dragonfly/releases/download/v0.10.0/dragonfly-x86_64.unstripped.tar.gz
and when it crashes run disassemble
I tried to run via GDB (in a container though), on a Celeron J4105:
