To start off, here is the pastebin of the log, the error here being [23:36:16] [main/INFO] [STDERR/]: [org.antlr.v4.runtime.ConsoleErrorListener:syntaxError:38]: line 13:0 token recognition error at: '`'. It should be noted that I got rid of the mod "Abscent By Design" which created errors in the past, but this error I'm not sure how to get rid of. I don't know how to code or programme. Any help would be highly appreciated. At the end, it suggests that  "An error report file with more information is saved as:
# C:\Users\newto\Desktop\Main\MultiMC\instances\All-the-Mods-6-1.5.3b\minecraft\hs_err_pid10948.log" Here is the other paste. I couldnt use pastebin for the latter as the website didn't allow me to do so.

The JVM crashed. Try updating Java.

Following this advice, I was able to boot the game and load into the world, only to have it crash again with a debug log that is 9,302KB in size. I then restarted the game, and it worked without crashing for about 10 minutes now, which is a massive win. I don't know why it works, or why it crashed, but I imagine this is what being a programmer is like, in any case, my initial issue is solved.
