Unable to complete theme installation on a clean WordPress Installation

Dear WPLMS Support Team, I'm trying to install your theme on a clean WordPress installation on a subdomain hosted in GoDaddy that I've set to have the following parameters: PHP version : 8.0 PHP Memory limit: 256 m PHP Upload limit: 128mb PHP Max execution Time limit: 300s I'm following the instructions step by step from this tutorial: https://youtu.be/C0RQO3-tjAI However, when the plugging starts installing, the BBB Appointment plugging fails, and automatically afterwards, I get a WhiteScreen error stating: "There has been a critical error on this Website. Please check your site admin email inbox for instructions." I am unable to deactivate the plugging from the cPanel as I have multiple domains under my cPanel. So I reinstalled WordPress on the subdomain with a new clean WordPress, but I got the exact same outcome with the same error. Can you please advise how to overcome this issue? I look forward to hearing from you. Thank you in advance, Ellie
