Minecraft test client won`t start

Hi I was using MCreator for a few weeks now and it worked all good but one day i tested it and it didn`t work i testet it a few times again and it always shoed the same message.

This happened to me when i used Mcreator in 2016 or something like that. I tried to rename the Cache.properities into Cache.properities.bin and in 2016 it worked but i did it now and the error log was like this:
