Not copy the correct ID

What can i do now. I dont want to delete the mod :-(

I add more stuff into the Mod. After i added the stuff and export the mod and run it. the mod didnt work annymore. Before i added the stuff it works

What can i do with run clint. If i klick on it after few second forge start to load the Mod (apart from the fact that it doesn't work) and i the Mod is loaded forge close and minecraft doesnt opened ?????

ok than is it my problem because the game crashed but there isnt a crashreport. i look in the phat minecraft / crashreports and there isnt a crashreport. Ok there are reports but from 2018 and the crash was today

in the erro massage is look into the log i found the log

i post it into the files

Bit i cannot post the original file i edit it from .log. to json but pleas open it in texteditor because it looks the same as the log file

it was in logs and i change it to json because i cant upload the log file

is the file helpfull?

can we close this issue because the problem isnt anymore but there is 1 other problem. The attacspeed doesnt change i have on the one sword attacspeed 1 and on the other 3 but in minecraft there is written attacspeed 1,6 what can i do? I updated the mccreator and my problme with mineraft crash isnt anyore
