Cannot boot Red Hat Remote Exam, hanging at 100%

I followed the guide for remote exam preparation, and am trying to boot my remote exam environment for DO288 but it just hangs at 100%. I've tried using different USB keys but I still get the same issue.

277848798_952113778826166_562151277569914448_n.jpeg

I know this has been a common problem in the past where others have resolved the issue by downloading the older version of the ISO https://static.redhat.com/downloads/training-certification/rhrexboot-2020-08.iso, but even the 2020-08 version of the ISO doesn't work for me. I just get a black screen when I try to boot the 2020-08 version.

Has anyone recently encountered the same issue or are there any new fixes? If it's at all relevant, my laptop is an ASUS ROG Strix G15 (2021) G513QE-DB91-CA.

Same here on a Ryzen 5600X system.

 

I think has something to do with AMD CPUs.

I got reply 

"Unfortunately, it will be impossible to say at this point as to whether and when a LiveUSB compatible with AMD Ryzen or Gaming laptops and other such hardware will be developed. Hence we cannot commit a timeline. For all cases of incompatibility, the recommendation is to take the exam from conventional classrooms or authorized testing centers."

 

"Kirthiram J (Customer update) Hello *****, Thank you for reverting back to us. Red Hat has to cope with some security concerns and challenges to protect its intellectual property and exam consistency. Creating a system bootable on the entire ever-expanding group of hardware is a difficult task, especially meeting the above-mentioned security and other criteria. The Remote Exam ISO is a spin off from the regular Fedora WorkStation 32 base image. We get a lot of candidates who have high-end gaming systems or the latest generation Apple systems that do not work with Remote Exam LiveUSB. It is a challenge to test various hardware available in the market and to develop an ISO compatible with all of them, our developers are doing their best to make the ISO compatible with the most commonly used systems. I suggest using an alternative system that works without issues with Remote Exam Live USB else you can even schedule the exam at the nearest testing center (some exams may not available at testing centers and are exclusively offered as Remote Exam) Regards, Remote Exam Readiness Support Team"

 

Dear Sir,

I already shared pictures in first email, nothing loads after 100% it's just stuck.
 
I believe though laptop is gaming laptop, technically it has all the resources which is required for the exams.
 
1. AMD Ryzen 7 is x86-64 family 
2. 16GB memory 
3. Dedicated LAN ports and USB ports
4. webcam
 
There are lots many users with AMD CPUs struggling to load exam on their laptop. if you could escalate this matter further with top level development team and help in releasing AMD compatible build it helps a lot.
 
I believe being pioneer in the industry Red Hat should be able to do justice on this matter.
 

Good Bye Red Hat from my side its very disappointing !!!
