It says at the bottom you're using a version built in Nov 2021, you might just need to update to the latest release (latest Arch release is 4.23-1, built 10-29-2023).
If the version in your repos is that out of date though (you didn't state your distro so there's no telling offhand), your best bet may to be to build it from source and install it.
