Fresh install of nodebb v4.2.0 on Ubuntu 22.04 with node v18.20.7. The forum appears fine, but when I log in as the admin user and go to the admin area, I just get a message:

Internal Error.
Oops! Looks like something went wrong!
Invalid Version: N/A

logs/output.log shows this whenever I go to that page.

I've tried re-running nodebb build and also completely re-installing. Any advice appreciated.
