How did you install bat?
zypper in bat
I also tried bat-v0.26.0-x86_64-unknown-linux-musl from the release page and encountered the same issue.
If I use the previous version bat-v0.25.0-x86_64-unknown-linux-musl it work as expected.

Does the same thing happen if you clear your LESS env var? What about using BAT_PAGER=builtin?
If I unset LESS it's still broken, however if I export BAT_PAGER=builtin it works
