Alt-Tab and Workspace Switcher shortcuts aren't working on Xubuntu 21.10

I have switched from Ubuntu Desktop to Xubuntu desktop because Ubuntu no longer supports desktop icons. Unfortunately, in the move I seem to have lost the ability to cycle windows with Alt+Tab and the ability to change workspaces with Ctrl+Alt + cursor keys.

I've tried:

checking the contents of ~/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-keyboard-shortcuts.xml: it has the expected (and confusing) contents that seem to work for everyone else

changing the key definition in Settings → Window Manager → Keyboard. Even deleting them, logging out, logging back in, redefining them makes no difference.

checking that the keys on my preferred keyboard are generating the right scan codes using xev.

There may be some conflicting setting hanging about from the regular Ubuntu installation, but I can't locate where they might be. I have tried the answers in How to restore app switcher hotkey Alt Tab in xfce4? to no avail.

I've solved this, but not in a way that identified the cause.

Because this is a system that's been upgraded through many versions of Ubuntu Desktop (possibly starting with 16.04), and now migrated over to Xubuntu Desktop 21.10, my ~/.config folder was full of extraneous and perhaps contradictory junk.

Here's how I resolved the issue:

moved the contents of ~/.config to a new ~/Desktop/dotconfig folder

logged out

logged back in. At this point, Alt+Tab started to work again, confirming that there were conflicting configuration settings before

Carefully restored files/folders from ~/Desktop/dotconfig back to ~/.config that I knew I'd have a use for. Any new files or folders in ~/.config that Xubuntu had recently created I didn't overwrite.

There are a few settings that I still need to restore - I've lost my beloved Compose key bindings, for one - but the system behaves much more like I'd expect now.
