Comment (by SergeyBiryukov):

 Replying to [comment:1 drzraf]:
 > Could you please consider changesets r54349 and/or r54351 which weren't
 merged but are necessary to avoid the `rtrim(): Passing null to parameter
 #1 ($string) of type string is deprecated`

 Those changesets were merged in WordPress 6.1 and are still included in
 6.2.

 The deprecation notice could be triggered by a plugin or theme, does it
 still happen on a clean install?

 Also, looking at comment:133:ticket:54504, might be a good idea to confirm
 that the site did in fact successfully update to 6.2, e.g. by doing a full
 file comparison.
