Technic Modpack loads mods but crashes right after opening them

[Titominecraft12]

My friend is having a problem playing a modpack with me. Whenever he tries to run the pack, the launcher disappears and then reappears. I have tried differnet java versions and trying to up the ram, but it doesn't work. I have the paste bin logs here. https://paste.ubuntu.com/p/HXwxbTKPrg/

Unfortunately for you, since your CPU is quite old, you can't go past java version 8u51. http://javadl.sun.com/webapps/download/AutoDL?BundleId=98428

Should I uninstall the other versions of Java I have?

I have installed it and tried to run it, but I still run into the same problem

Wait, how old is your CPU?
