If no one answers your question at this specific AMD Forum try posting it at ProRender Pro - Blender AMD Forum -https://community.amd.com/t5/blender-discussions/bd-p/blender-discussions.
Even though that is for the Blender Plug-in for ProRender but there someone knowledgeable about Blender might be able to help you out.
I do know that AMD has made ProRender compatible only with the RX GPUs. All Non-RX GPUs are now not supported by ProRender within the last year.
NOTE: If you want to upload a file you need to use a website (Free or paid) where you can upload and download files or folder and then provide a Link to the file or Folder on your reply.
If the txt is small enough you can take a picture of it and upload directly into your reply.
In the old AMD Format you can attach files and folders directly to a reply but in the new AMD Format that feature has been removed.
