Xbox Series X Crashing

My girlfriend doesn't have a Reddit account but wants to ask if anyone else has been experiencing any crashes on Xbox Series X?

This issue has only started in the last few days and been crashing in the menus and in games. There's no pattern to the crashes and only does it on RL. We've tried the usual restarting the console fully and uninstalling and reinstalling but nothing is working. Epic games support aren't being helpful just sending links with things that we've already tried. Has anyone else been experiencing this or is it an isolated thing?
