Need Help with my keyboard and mouse in ps5

I've recently been playing Overwatch with a keyboard and mouse on PS5, and this has never happened before. I had to switch to a controller because I wanted to play with some friends using controllers, and when I switched back to keyboard and mouse from the settings and started playing, I realized the mouse wasn't working and I can't use it in game or in the menus. I tried playing other games like Fortnite to see if the problem was the mouse, but no, the problem is with Overwatch. Has anyone else experienced this or can help me? I would be very grateful for any assistance.
