That function certainly should exist:
psql (14.6)
Type "help" for help.
postgres=# \df tstzmultirange
List of functions
Schema | Name | Result data type | Argument data types | Type

pg_catalog | tstzmultirange | tstzmultirange | VARIADIC tstzrange[] | func
pg_catalog | tstzmultirange | tstzmultirange | tstzrange | func

My guess is that your server is not in fact PG14, but some
