The offending commit is 998a0aacd from Stefan.
The commit is supposed to fall back to ASCII symbol if the Unicode
variant is not available, but apparently the check failed for some
reason:

(defcustom org-agenda-current-time-string
  (if (and (display-graphic-p)
           (char-displayable-p ?⭠)
           (char-displayable-p ?─))
      "⭠ now ───────────────────────────────────────────────"
    "now - - - - - - - - - - - - - - - - - - - - - - - - -")
  "The string for the current time marker in the agenda."
  :group 'org-agenda-time-grid
  :version "29.1"
  :type 'string)

Stefan, do you have any idea what can go wrong here?

The only thing I can think about is warning in the char-displayable-p
docstring:
