E_ERROR after updating PHP version

Hi,

After updating the PHP version on my website I got an error in two Rank Math menus; I mean that everything works fine with the plugin except that I can’t access the Dashboard and General Settings menus … Every time I click on these two menus the option to save the “admin” file as a “PHP Script” format is activated (in the rest of the menus I can enter without problem).

I have already disabled, deleted and reinstalled the plugin as you recommend in another ticket with a similar error but the problem continues; I also reinstalled the previous version of the plugin and nothing, I still cannot enter the Dashboard and General Settings menus.

This is the message I received by mail with the error notification:

WordPress version 5.4.1
Current theme: Divi Child (version 3.25.4.1562601177)
Current plugin: Rank Math SEO (version 1.0.42.3)
PHP version 7.1.24
