This thread is resolved. Here is a description of the problem and solution.
Problem:
Try to in crease "max_input_vars" by adding code into wp-config.php
@ini_set( 'max_input_vars' , 4000 );
But it does take effect.
Solution:
In my localhost, the MaxInputVars is 2500, you can check it with your server provider, check how to increase MaxInputVars settings to 4000 or above in your webserver.

Hello,
I can login your website, but I don't see the problem you mentioned above:
I am trying to add a new select field to an existing custom post type's custom field group. Each time I click save it disappears.
I did test it here:
hidden link
Add a select field, and save, it works fine, see my screenshot: select3.JPG
And there was an similar issue about PHP version 7.3, which has already been fixed in latest version of Toolset Types plugin:
https://toolset.com/errata/php-7-3-shows-warnings-about-continue-statement-in-types/
Since you are using the latest version of Toolset Types plugin, it should not be an issue.
Please provide detail steps to duplicate the same problem, and provide a database dump file of your website in below private message box, you can put duplicator package file in your own google drive disk, share the link only, thanks
I have installed a new webserver(PHP 7.3.12) in my localhost, and import your database dump file in my localhost in a fresh WP installation + the latest version of Toolset plugins, it works fine, I can add the select field , and save the field group without any problem, see my screenshot: select4.JPG
So there should be other compatibility/server issue in your website, please try these:
In case it is a compatibility problem, please deactivate all other plugins, and switch to wordpress default theme 2020, deactivate all custom PHP/JS code snippets, and test again
if you need more assistance to locate the problem, please provide your website FTP access in below private message box, I need to test and debug it in a live website.
