Extension Installation Readiness Check Error Magento 2.3.1

There are several errors when I’m trying to install an extension (Slider Banner Module) for the first time. The picture below shows the error in the readiness check. I’m using GoDaddy > C-Panel > Magento 2.3.1 on Windows 10 with PHP version 7.2

Readiness Check Failure 1) For the Check Cron Scripts errors, I am able to solve it by manually change

$ setupCheck = $ this->cronScriptReadinessCheck->checkSetup();

$ updaterCheck = $ this->cronScriptReadinessCheck->checkUpdater();

to

$ setupCheck = ['success' => 1];

$ updaterCheck = ['success' => 1];

I’m not sure if that is the correct way to fix it since there are no .setup_cronjob_status and .update_cronjob_status files in var.

2) For the Dependency error, I have tried to remove "require-dev": in composer.json file but the error still persist.

3) For the PHP Settings Check error, I tried to change the memory limit in .user.ini and .htaccess from memory_limit = 756M to memory_limit = 2G, however, the C-Panel > PHP Selector > Options > Memory_limit still stays at 756M. PHP Memory Limit

4) PHP Extensions Checks is as the picture below (Default Value) PHP Extensions
