Ah, ok.  Sorry, I didn't know that.

No problem.  When I 'pp' the list, I see these 7:

 (\"nnfolder+archive:sent.2022-06\" 3 nil ((unexist) (seen (1 . 2)))
  (nnfolder \"archive\" (nnfolder-directory \"~/Mail/archive\")
	    (nnfolder-active-file \"~/Mail/archive/active\")
	    (nnfolder-get-new-mail nil) (nnfolder-inhibit-expiry t)))
 (\"nnfolder+archive:sent.2022-07\" 3 nil nil
  (nnfolder \"archive\" (nnfolder-directory \"~/Mail/archive\")
	    (nnfolder-active-file \"~/Mail/archive/active\")
	    (nnfolder-get-new-mail nil) (nnfolder-inhibit-expiry t))
  nil)
 (\"nnfolder+archive:sent.2022-08\" 3 nil nil
  (nnfolder \"archive\" (nnfolder-directory \"~/Mail/archive\")
	    (nnfolder-active-file \"~/Mail/archive/active\")
	    (nnfolder-get-new-mail nil) (nnfolder-inhibit-expiry t))
  nil)
 (\"nnfolder+archive:sent.2022-09\" 3 nil nil
  (nnfolder \"archive\" (nnfolder-directory \"~/Mail/archive\")
	    (nnfolder-active-file \"~/Mail/archive/active\")
	    (nnfolder-get-new-mail nil) (nnfolder-inhibit-expiry t))
  nil)
 (\"nnfolder+archive:sent.2022-10\" 3 nil nil
  (nnfolder \"archive\" (nnfolder-directory \"~/Mail/archive\")
	    (nnfolder-active-file \"~/Mail/archive/active\")
	    (nnfolder-get-new-mail nil) (nnfolder-inhibit-expiry t))
  nil)
 (\"nnfolder+archive:sent.2022-11\" 3 nil nil
  (nnfolder \"archive\" (nnfolder-directory \"~/Mail/archive\")
	    (nnfolder-active-file \"~/Mail/archive/active\")
	    (nnfolder-get-new-mail nil) (nnfolder-inhibit-expiry t))
  nil)
 (\"nnfolder+archive:sent.2023-08\" 3 nil nil
  (nnfolder \"archive\" (nnfolder-directory \"~/Mail/archive\")
	    (nnfolder-active-file \"~/Mail/archive/active\")
	    (nnfolder-get-new-mail nil) (nnfolder-inhibit-expiry t))
  nil))

I am weird :-).

I can also try to catch that in the debugger, if it helps.  Since
setting debug-on-error seems not to help, can I perhaps set a breakpoint
somewhere in Gnus?
