@umija5895m how in the world is this invalid??? This is a real problem im having and others as well

As noted above, the crash log is automatically sent to the developers by the Realms server.
Unless you can provide specific and repeatable steps that someone else (ie, the developers) can follow to produce a crash, there is no purpose in keeping a crash ticket open here on the bug tracker, because there is no way to know if a particular fix would apply to the ticket.

One suggestion I would have would be to try removing any add-ons, if any, to see if that helps.
