Thank you for reporting bugs and helping improve Blender! Every AMD graphics card that is GCN first generation or later can be used for running Blender [1]. GCN second generation or later is required for GPU rendering [2]. Unfortunately the AMD Radeon RX 5700 XT does seems to be affected by some technical issues, that are still under investigation. Might be a bug in Blender or an issue with particular OS, hardware and driver combinations. See ticket T75319 for updates on this problem.
