First time issues with stream after update? Grainy/Pixelated

Hi all, thanks for anyone that is able to help me. This is the first time i've asked for help here as I usually try to debug things myself but I am having some major difficulty here. I'm not sure exactly what I did that caused it but for the past week my stream has been very grainy/pixelated on movement. I normally stream with no issues. Particularly this is in FPS (CSGO, Apex, Valorant) all the same grainyness, even my desktop has a noticeable pixelation. I understand that this is normally bitrate related so i'm not sure if it's my internet. I've tried a few sites testing internet speed with varied results below:

Settings:
Video bitrate: 6000 kbps
Encoder: Hardware (Nvenc)
Audio Bitrate: 160
Encoder Preset: Quality

Base Canvas: 1920x1080
Output (Scaled) Resolution: 1600x900
Downscale filter: Lanczos (I've tried Bicubic as well no difference)
FPS: 60

I have also used the twitchtester to find the proper server and that has not helped either. I have tried to downscale it to 720p, changing bitrate with no success.
I have been streaming fine for the whole year but lately I am not sure if I messed with my cpu settings, or if it's because I updated my OBS studio. I havent updated it for months, but since around the time of update I have noticed the grainy/pixelated images while moving. I am honestly lost here and really considering if it is just an internet issue. There was an outage about a week or so ago which may coincide with when the streams have started to have issues. I appreciate any help, thank you.
I have attached my log here: https://obsproject.com/logs/aOP0BBY6-ohsFQa2 (This log was in Apex, normally I have no issues with these settings).
 
There are a bunch of issues in your setup that may or may not be related. It's a fairly large list so need to know if you want them all taken care of or only what you want fixed.

I will be willing to fix all that is needed, I would appreciate any help that can be provided. Thank you
 
First, the reason you're having issues is that your internet connection is very unstable, as the following in the log indicates, and may require contacting your ISP:

08:54:23.847: [rtmp stream: 'simple_stream'] Dynamic bitrate enabled. Dropped frames begone!
08:54:23.847: [rtmp stream: 'simple_stream'] Connecting to RTMP URL rtmp://iad03.contribute.live-video.net/app...
08:54:23.877: [rtmp stream: 'simple_stream'] Interface: Intel(R) Ethernet Connection (7) I219-V (ethernet, 1000 mbps)
08:54:24.800: [rtmp stream: 'simple_stream'] Connection to rtmp://iad03.contribute.live-video.net/app successful
08:54:24.826: ==== Streaming Start ===============================================
08:54:37.191: [rtmp stream: 'simple_stream'] bitrate decreased to: 3900
08:54:41.547: [rtmp stream: 'simple_stream'] bitrate decreased to: 3800
08:54:45.148: [rtmp stream: 'simple_stream'] bitrate decreased to: 2800
08:54:46.685: [rtmp stream: 'simple_stream'] bitrate decreased to: 1200
08:54:51.047: [rtmp stream: 'simple_stream'] bitrate decreased to: 500
08:55:21.050: [rtmp stream: 'simple_stream'] bitrate increased to: 900, waiting
08:55:27.633: [rtmp stream: 'simple_stream'] going back to prev bitrate
08:55:27.633: [rtmp stream: 'simple_stream'] bitrate decreased to: 500
08:55:57.642: [rtmp stream: 'simple_stream'] bitrate increased to: 900, waiting
08:56:10.000: [rtmp stream: 'simple_stream'] bitrate decreased to: 600

Secondly, these are all the other issues I have found with a quick glance:

1) In Windows 10 settings, disable "Hardware-accelerated GPU Scheduler" and "GameDVR" then enable "Game Mode";

2) In OBS Settings --> Video, change Output resolution to 1536x864 (I'll spare you the technical reasons for this);

3) You do not have a scene with fullscreen camera so reduce camera resolution to 720p or even 480p, depending on how much of the scene it covers;

4) Multiple capture sources in the same scene will, at best, reduce performance or, at worst, interfere with each other. Create new scenes so each one has a single capture source;

5) In OBS -- >Output, use NVENC, "Quality" preset, "CBR" rate control, "6000" kbps bitrate, "Lookahead" and "Psycho Visual Tuning" disabled.

Thank you, I have fixed the issues you have mentioned. Unfortunately, the stream is more or less the same. I believe it must be the internet as the kb/s on the bottom right of the obs display is also fluctuating a ton. My upload seems to have varying range from 2.7mb - 10mb+. I will be contacting my ISP soon. If there is anything else that may help I would appreciate it. Thank you very much for your help.
