Your game is not crashing, the logs say that you are crashing it manually (F3 + C), but you are experiencing an error where Xnet could not encode "the custom payload" you mentioned due to a bug where empty item stacks are created, most likely from mod conflicts or coding issues with it.
Reinstall the modpack to fix possible corruption issues.
If that does not work:
Try disabling Xnet first and start up a new world to see if the issue gets fixed. You will not get the features of Xnet, but it might be the only way to fix the problem. If it is, then the modpack owner will need to remove, configure, or update it to fix the issue you are having. You can search for the latest version of Xnet and also its required mods to fix it yourself as well(not guaranteed to work)
TLauncher is bad and should not be used because it has potential malware and supports cracked versions of Minecraft. You can use it, but, if you want the best support without any malicious software or cracks interfering, find a reputable launcher, though, buying the game is the best option if you have money.
I cannot give you an exact issue of why this is happening because I am not the owner of this modpack.
This is happening in my world as well. This needs to be remedied by mcjlty as soon as they get a chance. Or if ATM team could just disable the xnet storage channels via config, that might work too. Currently cant click the controller either because itll attempt to read a storage channel that isnt there.
Just tried to break the xnet controller and that made it significantly worse. I now can't login because my client crashes immediately.
Please put your logs so that it's easier to fix the problem, or just remove/update the xnet and its related mods or try avoiding them where it's not needed.
