I've been trying everything to get Minecraft to work since this recent update.

I updated Java to the most recent version, and I tried to update my graphics card but it said I could not meet the minimum requirements for updating it as my computer is a bit old.
It takes me about 5-10 minutes to open Minecraft in general, and then I go to enter into my realm and it crashes. Now, at first it crashed the second I went in and gave me the "Java (TM) Platform SE binary has stopped working" error. I messed around with a lot of things and eventually I was able to get it to where I can enter the realm and move around but it crashes with no error or warning at all after about 30 seconds or so of me moving around.
I've tried other things as well, such as going into single player, it does the same thing.
I tried going on a past version and it did the same thing as well, I tried entering multiplayer and none of that worked. My friend who is very good with computers told me it might've been updating Java so I went to the previous version and still no luck.
I turned off the newest texture pack added on to be on the original texture pack and I also have all of my minecraft settings down to the lowest settings possible.
I've also tried to clear out my .minecraft folder in order to have it redownload everything and it didn't work either. So as a last resort, I'm coming here to ask if there's anything else I could possibly do to make it work or if it's just a bug and I need to wait until bug fixes are released.

Thank you!
