suiteCRM 7.11x & 7.12 issue using php 7.4

Hi there,
in order to use a certain plugin I had to switch from php 7.3 to php 7.4. Although according to the compatibility matrix: Compatibility Matrix :: SuiteCRM Documentation everything should work fine I encountered some issues when I go into the studio and try to edit some fields.

The message I’m getting is:

Warning: Creating default object from empty value in D:\xampp\htdocs\suiteCRM\SuiteCRM-7-xampp\modules\ModuleBuilder\views\view.modulefields.php on line 109

I did a little bit of research and it seems this problem should have already been fixed in the past

Test environment is:
suiteCRM 7.11.21, 7.11.22 & 7.12 RC
PHP 7.4.25
MySQL 5.7

Anybody else encountering this problem?

PS: everything worked as expected when using PHP 7.3 but as I mentioned before I need PHP 7.4 for the plugin

update:
found another thread having the same issue
