With all the problems you have encountered from several posts.
From server issues changing php and sql versions
Have you double checked your php
max_input_vars
max_input_time
max_execution_time
To make sure they did not get reset to a small value
They did get reset. I had to change several values that were reverted to the default. Compounding the problem was that I was editing /etc/php.ini when AlmaLinux puts the actual file in /etc/opt/remi/php83/php.ini. I discovered that when I looked carefully at the php info page after my edits had no effect at all.
Why some linux versions insist on putting things in non-standard places is a question I'd like answered. But I'm sure some techs will have a logical explanation for ignoring decades of wisdom.
