The game crashes sometimes and it seems to have something that Java dont have enough space or something, I dont know were I fix it... I have runned the Java application but I cant find were to fix it. I would be very thankful If I could get some help.
Here is the crash report.

Are you using the curseforge app? i recommend it. use 8gigs+ for a good experience

I use Curseforge and have it for 12 gig now but the game still crashes sometimes.

According to the log, your systam only has 8 gb of RAM, so it crashes when you set it to use 12, which are not there.
For 8gb I'd say you should set it to an absolute maximum of 6.

I have been running it on 8 gb since yesterday and it hasn't crashed anything, thanks for your explanation. 😊
