This issue started on my online development site after updating from 14.0.0-RC2 to 14.0.0-RC3, suggesting that it's related to the update process. I’ll perform a fresh reinstall of version 14.0.0-RC3 to see if it works properly. However, I have yet to find a version that updates automatically without issues. This raises concerns about the reliability of the update process. After all, who would feel confident investing in a website that can't be updated smoothly? To be honest, I still don’t have the courage, even though I really want to.

A fresh install of 14.0.0-RC4 resolved the error, confirming that the issue stemmed from the update process and previous versions. Thanks @LeonidS we can close this ticket
