FreeBSD 14.0 will include OpenSSL 3.0 in the base system, and one or more ports that you maintain failed to build in the exp-run. Please see PR271656 (https://bugs.freebsd.org/271656) for build logs and details.
bofh@ has recently committed some fixes/workarounds and might be able to provide advice on updating ports; ideally we can also provide some general advice on the mailing list in the near future. For now you may just want to check your upstream project to see if there is an open issue or an updated version for OpenSSL 3 compatibility. Best Ed
