FreeSync causes black screen after monitor goes to sleep

So here's what happens. FreeSync will work fine when I turn it on and launch a game and play. But if my monitor ever goes to sleep FreeSync gets messed up. If I turn on a game after my monitor has been to sleep at anytime, my screen will be black but you can still hear the game sound. Minimizing the game lets me see my desktop again but if I go back to the game it turns my screen black again. It's like my monitor is off. The only way to fix this is to turn FreeSync off and then on again and it will work as intended. But if my monitor ever goes to sleep again it will start doing the black screen when I launch a game and I will have to turn FreeSync off and on again. How can I fix this? My monitor is a Pixio PX248 and my graphics card is a MSI Gaming Radeon RX 5600 XT.
