Thank you for responding. Sorry it took me so long to respond myself.
I will gladly give you details only because i actually love your game.
Before i start i want to make something crystal clear. What i say here and below is only for CO-OP and has Nothing to do with playing solo. Understood? When i play solo the game runs flawless 99% of the time. The issues below appear when i am in group co-op ONLY. Usually in trio because its what i get matchmade in the most. Though duo also has the exact same issue too just maybe not as bad as in 3 man. It doesn't matter Who i matchmake with. It can be my sister in the same house or someone across the world/country from me. Co-op is busted.
I took the time to actually make you some videos. I hope you appreciate the effort and actually watch them as it will show you EVERYTHING that is going on in Co-op. "You can also just matchmake yourself and see yourself too". I can garantee you that if you matchmake in co-op you will experience this in some very of degree. None the less here we go:
-In this Video below i upload a complete run. This is your typical co-op experience in 3 man. Give or take. This also shows some of the worst that could happen at times.

1) 25sec The Roll glitched out
2) 32sec Alpha lagging all over the place
3) 37sec - 1:10 EXTREME stutters, lag, unable to move, d-sync etc etc "This is the worst"
4) 1:10 trying to enter the circle causing more of number 3. "Note: this isn't limited to just within the circle. i have had this in many parts of the game it just so happen that this time it happened in the circle which is known buggy area more so then other areas"
5) 2:15 more of the above
6) 2:30 Hunt the prey is in this weird slow motion lag feeling
7) 2:37 hunt the prey is in this weird slow motion lag feeling again
8) 3:30 stutters, lag are d-syncing me all around
9) 4:25 hunt the prey lagging and delaying after pressing
10) 4:42 hunt the prey not working
11) 7:41 hunt the prey bug
Just watch the whole video to take it all in.

-Here's a short clip at the end fight on Scorched Lands. Up until this point the run wasn't actually too bad. Other then a couple slow hunt the pray teleports, 1 60FPS drop bug and a couple d-syncing npc all was going good until this point. However, once we got the cut scene that drains the water to allow us to then go down there we all got rekt. Huge lag stutters that made me walk slow and jerk around, NPC bugging out, skills not working etc. just watch it. "Mind you i was trying really hard to get out of this zone but the game kept fighting me and pulling me. The NPC also dint help" and when i finally got out it was just to late. The other 2 players got it just as bad. We where doing just fine up until that point. So for them to die too they had to been experiencing the same thing as me. (If i had to guess something with the water draining caused all these issues on this run in this area) Like i said This is not only limited to this expedition or this area. Ive had this happen to me many time. But in this case it might have something to do with the water. (This is on the worst side of issue)
Side note tangent: Please for the love of god fix that stupid Toxic prompt Hint that constantly pops up when you get acid applied. Or let us disable it or something. It pops up like 4 times in this clip of only 1min 25sec long. errrr

Clip 1: I use hunt the pray and then get stuck in this weird humping animation. Ends at 12sec
Clip 2: Same as Clip 1. I use hunt the pray and get stuck into this hump animation. rolling seems to get me out of it. Ends at 25sec.
Clip 3: at 27sec i use hunt the prey and lag in one place before it TP me. "This happens alot" at 32sec hunt the prey is still on cool down but it does a hunt the prey effect/animation and finaly at 36sec again i use hunt the pray and it lags/delays the Teloport. Ends at 40sec.
Clip 4: 42sec hunt the pray doesnt work and have no idea what its doing. Ends at 45sec
Clip 5: hunt the pray laggy slow motion teleport. Ends at 50sec.

Clip 3: Notice broken 60FPS drop bug "I have to hit emote wheel or esc to return my fps to 120fps"

-Last short edit video:
https://www.youtube.com/watch?v=Eq90QSMd34I&ab_channel=VapoorerGames
Clip 1: This cut scene and clip i actually crashed. notice FPS drop. I crash bc after the FPS drops it instantly hits my PC with full load 120FPS. In other words it goes from 120FPS down to 10FPS then trys to return back to 120FPS but crashes. "Lowering the cinematic FPS to 60fps doesnt do anything" game still crashes most of the time. The only way to not crash is if i fully tab out of the game while the cut scene is on. Then when the game returns i tab back into the game.
Clip 2: is me just moving around. Notice the stutter jerky d-sync lag.

-Not my Video: I found this video also showing someone getting one-shot when they still had HP left. Oddly enough whenever i did get that random one-shot i too also always had HP left. Sometime almost full HP:
