Cannot load world (help)

[Jah_Phrog]

My friend and I have been playing in a survival world for some time (over 100 hours) and we had just finished building a very big house. We needed the roof to be oxidized copper so we set the tickspeed up and noticed a lot of zombie piglins spawned because of the tick speed, so we started messing around to spawn more piglins but ended up setting the tickspeed to a billion. Over 5000 piglins are in one spot and has destroyed our worl. It has become impossible to join the world and we need to know if theres a way to get rid of the piglins or change the difficulty without joining.

So far we've had a friend join to fix it but that didnt work and we used the console and settings on the minehut website

If anyone knows how to fix it please let me know I don't want to restart especially after spending 15 hours building a house just to lose it immediately.
