Playing roblox makes my monitor turns off

Simply whats in the title. Playing roblox with my graphic card(RX580) makes my monitor turns off, I tried all fixes that I could find on reddit - reinstalled roblox, reinstalled drivers, changed roblox rendering mode, downloaded roblox from microsoft store. Nothing that I wrote here helped me. It happens on a random moment - I am just playing and suddenly my monitor turns off, and the only think I can do is emergency shutdown and turn on my computer back, but I am pretty tired of this. Any solutions for this?
