Installing TRAMP with package.el fails on startup

Hey,

I'm using 'GNU Emacs 29.1 (build 2, x86_64-pc-linux-gnu, GTK+ Version 3.24.38,
cairo version 1.16.0) of 2023-08-30, modified by Debian' with ...

(setq package-install-upgrade-built-in t)

... set in order to update built-in packages. Updating other build-in pacakges
seems to work, except tramp (2.6.1.3), which installs without errors, but
produces errors on emacs startup, like:

Symbol's function definition is void: tramp-register-crypt-file-name-handler


When running emacs with --debug-init I get this trace:

Debugger entered--Lisp error: (void-function tramp--with-startup)
(tramp--with-startup (add-to-list 'tramp-methods (cons tramp-adb-method (cons (list 'tramp-login-program tramp-adb-program) '((tramp-login-args (... ...))

Perhaps the TRAMP loading conflicts with built-in TRAMP or some order of
loading is needed?
