I recently had to reinstall Minecraft because it was instantly crashing upon opening. Luckily after reinstalling that issue has been solved, but when I try to add a custom skin the game crashes. I can click on the custom skin icon and select a skin file, but when I click the file the game crashes. When I open the game back the skin is reset back to Alex. I've tried multiple different skins with same results. I've also looked at a lot of other similar posts and haven't gotten a solution.
