Hi Helena,
Great. Thanks for trying that with your AMD GPU. Sorry, it didn't work. Can you give us a bit more info about your CPU? Is it an Intel CPU or one from AMD? Which model is it? Are you sure you do not have an NVIDIA card installed in addition to the AMD one? Sorry to ask so many questions.
A clean reinstallation of AMD Drivers may help: https://www.amd.com/en/support/kb/faq/gpu-601
