GPU Accalerated rendering error

Hi! I`ve recently installed a new AMD Radeon rx 6800 GPU with 16gb VRAM (combined with ryzen 7 3700x 8core CPU and 32gb of RAM). When running rendering in media encoder or within premiere, with GPU accelerated rendering i keep getting the export error: 

"Error compiling movie.

Accelerated Renderer Error

Unable to produce frame."

While researching the problem it looked like this could happen with a slow gpu, and it was reccomended to run rendering on playback engine software only (https://community.adobe.com/t5/premiere-pro/premiere-pro-cc-quot-unable-to-produce-frame-quot/m-p/8396548#:~:text=Accelerated%20Renderer%20Error-,Unable%20to%20produce%20frame.%22,you%20are%20trying%20to%20perform.&text=Normally%2C%20encoding%20does%20not%20engage,Lumetri%20color%20effects)%2C%20etc.)

Although rendering alot slower, this helped... but surely a new and high end gpu as the rx 6800 should handle this?

Any help is very much appreciated!
