Hi Ofi,
Sorry, my dev server is not accessible right now but I'm working on it with our IT.
Anyhow, I enabled debug and here's the screen capture:

I am running PhP 8.0, I don't know if that's relevant info as there are issues with Php 8.0 with module. If you are running Php 7.4 and don't have this issue with vanilla J4 and Helix Ultimate then it might be a php issue.
Is it possible to request from your dev team to add PhP 8 support to SPPB v4 earlier? I am actively developing our website using SPPB v4 so when it finally released I could publish our new website as well. Waiting for the stable release for Php 8.0 support might bring another layers of bugs. Also, I hope it's possible for them to work on the SPPB Module as well on each release.
Thanks,
Jackson
