Processing Crashes when I try to open a file

As the title says, processing crashes immediatley when I try to open a sketch and returns a Null.Pointer.Exception error and will not respond. I am using Linux Solus and have been using this program fine until one day this happened. Not sure how to work around it or if theres a serious bug in an update.

Are you opening a specific sketch or just any sketch?

Just to clarify, this is to open a file and not run a sketch, right?
