Unfortunate

After 20 to 30 minutes of playing my game will crash. It is a modified version of RLCraft with all the mods updated and some more mods added. There is no black screen, lag, or freezing when it crashes, just straight from gameplay to the Minecraft Launcher. I have already tried removing some mods mentioned in the log and de-locating some ram but nothing happened and after I removed some of the ram it got worse. I have tried all I can and I don't know what to do anymore. I could use help. I attached the debug and latest log but had to shorten them in order to send them. latest.log debug.log
