Just to clarify, is this showing up only as a warning in the logs, or is it also affecting how your site works?

This code shouldn't generate a warning thoug:

Xss::filter((string) $toc_js_settings['back_to_toc_label'] ?? '', ['span'])

Are you sure you are on latest 3.2.1 version?

EDIT: Ok, it looks like the cast takes precedence over the ??, could you try adding some parenthesis around to see if it fixes your problem ?

Xss::filter((string) ($toc_js_settings['back_to_toc_label'] ?? ''), ['span'])

Created an MR with the fix.
