Recently I've been having issues to load up the modpack I've been playing for a bit over a year now, I still have the same computer I had when I first started playing and it ran smoothly, but recently I started to lag and now it just isn't loading at all anymore, instead I get an ERROR message. It does seem to only affect the modded version of Minecraft as my normal Minecraft has no issues loading. I'm open to all suggestions, but please do give me somewhat of a step-by-step guide that way I can make sure I do it right so the issue can be solved.
Here is the HijackThis log, I do hope this will help understand my issue a bit better as I have no idea what to do.
