XF 2.2 setup issue

[AxolotlStudios]

error on setup, didn't edit anything, followed the instructions on this: https://www.knownhost.com/kb/install-xenforo-manually/
and when I tried to create the admin account, I got this:
LogicException: Class XF\Service\User\UserGroupChange does not exist in src/XF/Container.php at line 273
