player desync/lag during boss fights/normal gameplay

Recently me and a friend are having issues with lag, and not like stuttering lag. everything runs fine until for me (the host) my friend just starts running in place on my screen, or just moving in the direction they were before. this is completely desynced from what my friend sees, the game still runs and she can fight and beat the boss but cant get any drops nor return to normal gameplay once the fight is over. On my end the boss will endlessly try to kill my friend (where she is on my end) and i can still damage it and stuff shes just stuck for me. it makes the game entirely unplayable to help would be greatly appreciated. I didn't see much in the logs except for "Object reference not set to an instance of an object" and when looking in Server.log it shows this*...

Trouble installing versions from github

I downloaded a specific version of tmodloader off of github, and tried following the manual installation guide (https://github.com/tModLoader/tModLoader/wiki/tModLoader-guide-for-players#manual-installation) but I am finding it confusing to understand some specific steps and would appreciate if someone could guide me through it.

generate modded structures/biomes on existing world

Is there any way to generate biomes and structures onto existing worlds? cant create a getfixedboi seed with my mod collection and cant figure out which mod is breaking world creation since logs just have the normal "generating gem structures" as last message before it crashes/gets closed. so is there a way for that? or do i need to "world edit" the modded stuff into a vanilla getfixedboi world? https://steamcommunity.com/sharedfiles/filedetails/?id=3050294334 this is the mod collection used. have tried disabling near all mods and cant find which one causes the problem/crashes...

Question about the "Mod Side" type meanings

Is there some kind of clear documentation somewhere on exactly what the different "Mod Side"s mean? Client and Server seem self-explanatory, and I'm gathering that "Normal Side" in the in-game browser means the same thing as "Both" in the steam workshop. What I'm really confused about is "NoSync". I see mods like "Start with base" that make sense as they would only matter during world generation, but then I see mods like "Better Boss Health Bar" which seems like it could just be client side, and "Improved Movement Visuals", which I'm reading from the description is optional, but if installed on client and server very much seems like its syncing things up. Is that maybe the key behind the "NoSync" terminology? Which is that it provides server-side functionality and requires client-side code to function for a particular client, but isn't required to actually have installed in order to join a server? I think that makes sense now that I've typed it out, but would like some confirmation if that's the case. Impetus behind the question is that I'm looking at setting up a server for some friends. I understand that when they join their tmodloaders will install any mods that are missing on their end (I believe this is based on the contents of the "install.txt" file), which should include any mods that are "Both"/"Normal" side, and each player can have client-side only mods in addition to that if they choose, but how do NoSync mods interact with this?...

World file and backups are missing, onedrive is disabled

My world file did not save last night when I stopped playing, onedrive cannot be the cause of this as I disabled it a long time ago. I used TEdit for the first time last night though, so it could be microsoft defender causing the issue? I have only a small number of quality of life mods enabled.
