Red Flashing Mojang screen

Ever since I had got the new 1.16.201 Minecraft hasn't been working. I go to click on it and then the Mojang screen appears and then it goes to red and starts flashing from red to white. I have epilepsy and it's kind of seizure inducing. I've tried uninstalling and re-installing, but nothing works. Please fix this bug as I wish to be able to play again
