Apparently It's a freesync bug. When I disable FS everything works fine, even the software that doens't open before, now open.
My config: Ryzen 3 2200g, Rx 570 powercolor 4gb, 16gb ram 2733mhz, CX450w, HDD 2TB 7200RPM, SSD Sata Kingston 128GB.
Windows 10 64B Pro ver 1909. Latest amd driver installed, currently: 20.2.1.
My monitor: Samsung 24" Curve, model number: C24F390.
Hope you can help me.
