No XBL Issues only EA Error for Apex on Xbox One S

"Connection to server timed out"

I have been getting all types of EA errors that have been booting me from lobbies an I feel like I am losing my mind at this rate. I have been on Xbox for over 13 years an I have never had issues like this with any game, other games work fine. I have tried looking on here for ideas as to what it might be an it seems there are a lot of people having the same issue as me but they're either on PC or the PSN. 

Someone had said it may be lag on my end but I know what lag looks like an this isn't it. I'm only having this issue with Apex Legends, the problems have gotten progressively worse since the Train Event came down, I thought the Fight Night event update would fix this issue but it has not. I have uninstalled the game 4 times this week an each time I deleted it I also removed other games thinking it may be an issue with memory but that hasn't worked.

I do be connected to XBL parties with friends while we play an I can call when I'm about to be errored. It feels like the errors happen the closer I get to other players as if too much is happening at once for the game to cope and if I bump into a Horizon that uses her gravity lift this also causes the game to freeze. Sometimes I get rendering issues like the floor not loading, Hedges, Bike Shelters, Care Packages and even other players that I blindly run into. I have a friend I play with who plays the audio through his TV an I can hear my characters callouts through HIS microphone and all my audio that cuts out whether it be opening a door, picking up a weapon, marking something an even shooting all comes crashing down at the same time in my ears like 40 seconds after the fact.

My game audio is cutting out, characters are stuttering on the character select screen, I go to reload an my gun an mag stutter for 10 solid seconds before I can reload. it is impossible to enjoy playing because I am just waiting for the error to boot me.. I never lose connection to Xbox Live or the party chat which would usually be the case if the internet was an issue.

I had seen a fix for PlayStation on YT which has got to do with manually setting the DNS to a certain address an that had worked for about 4 days before it reverted back to this nonsense, it seems the more I play the worse it gets an it's unfortunate because I like to play Apex. I'm wrecking my own head by constantly resetting my modem an clearing the Xbox Cache an at this rate I'm done... It's definitely not my internet or the Xbox.

I would just like to play a normal full round on Apex.. instead of  EA Erroring 4 times from 1 game.

I get so many different error types that don't make sense to me, ones that mention Steam/Origin and Xbox 360 Sign in Errors but the funny thing is I've never played Apex Legends on the 360 an I haven't touched a 360 in years. I also don't play Apex on my computer an have never even tried to download it.

I'm surprised I am still trying to play this every day an I do be lucky to play a full round but the enjoyment has been sapped due to these unstoppable errors.

Edit; Errors include;

(code: net)

(code: leaf)

(code: pakfile)

(code: 0XFFFFFFFFF)

I've received other errors but they would disappear as quickly as they popped up so I could never screenshot them.
