game crashes for second player after host updates a mod ?

[Oke518]

hello all me and a friend have been playing a new world since 1.16 and have run into a strange thing that happens when "i" the host of the Lan game update mods. when i update a mod i.e. delete the old zip and put in the new one then relaunch the game it runs perfectly fine for me in every way signal player/Lan/internet. but if my friend try's to rejoin the world his game just crashes to the desktop full stop only deactivating the mod/ down grading will allow them to join again. we have a lot of time in this world and would love to not have to restart. any ideas?

This is the friend in question. I've copied the error message I was getting when trying to join, hope this will help:

Are both of you using the same exact game client release version AND the same exact mod file versions on each computers at the same time?  Your comment reads that you are upgrading a game modification file, then running it while your friend is not using or hasn't  updated the same modification file on their computer. Both computers need to use identical game client versions and mod file versions to ensure compatibility problems are minimized during multiplayer or co-op games. Ensure that the game client version and the mod files version are identical on both computers first and see if that resolves the problem.

We figured out it was a problem with mod synchronization. Deleting the mods in the multiplayer save folder and redownloading it when I connect to my friends server again fixed the issue.
