What do you mean by 'curseforge Minecraft crash report'? I assume the game has crashed and your after a crash report and your using the Twitch Launcher or you have a Forge/Minecraft crash issue? Crash reports can be found in the crash reports folder of your directories (if Minecraft it's .minecraft/crash reports, if Twitch it's in it's instance. If you can't see much of a crash report or want to paste it elsewhere try hastebin or a similar to put them and put the link somewhere. Otherwise I guess a .txt document would do.
