Please help a total Drupal/PHP noob out. I'm a student modifying a site that my organization inherited, and the site keeps encountering an error every time I try to add necessary modules to the site:

In Drupal market place the session limit module is available for Drupal 8.x version only.
Still now it is not release for Drupal 9 as per Drupal official community. In my current project(Drupal 9), there is a requirement,
which might be fulfil by this session limit module. But I have one concerned regarding this module,
does this module is compatible with Drupal 9 or not? Since, still there is no any official communication
from Drupal market place yet. Could you please suggest me, so that I can proceed this module with Drupal 9

Hello Everyone, 

I have tried installing Varbase Hero Media Slider today and later on I found out that it wasnt compatible with the latest drupal version I'm currently using. Therefore, I had decided to remove it through composer since it wasnt installed. After removing the module I'm unable to access the modules page as it says Page Not Found. 

I would highly appreciate it someone could help me out on this.
