I have been playing Minecraft on pc for about a month maybe less after I made the switch to PC. And it was working fine for a while then it suddenly started acting up. it would open 2 tabs on MC and they both would be black when I would click on them they would say not responding. So I tried deleting it and redownloading it but that had no effect then I tried looking it up and then tried troubleshooting in the properties of MC and anything I did had no effect. If i could get some help that would be great.
