I honestly had zero issues with streaming up until the last few updates. main issue is Youtube shows me this warning. - "YouTube is not receiving enough video to maintain smooth streaming"
I sorta understand that my upload is low, but like I said I never had issues before. Seems this also happens when I am Recording my stream. I have the output for recording settings pic below as well and I have also have Process priority Above Normal as many threads have suggested. Im lost boys. anyone out there have a way to fix this? Thank you so much in advance.

12 mb/s upload isn't that low... unfortunately (US cable market commentary) ... as long as you understand speed tests do NOT report average low threshold... which is the metric you need to know for streaming. So your actual usable upload bandwidth for streaming is less, by how much? depends.. And depends on all other network devices network traffic as well. Is you computer the ONLY device on home LAN? presumably not... right? in which case you need real-time monitor insight into all other outbound WAN traffic at your router... you coudl simply be running into bandwidth conflict with other users/devices at home
- that isn't a cellular WAN/ISP link is it? if yes, own whole separate other issue.

That CPU is really old (8/9 generations old.... I'm running similar, but NOT for real-time video encoding). You need to make sure Operating System is optimized for performance in terms of reducing unnecessary background tasks (which one? depends on your specific circumstances) RAM consuming browser sessions, apps with background networking (like a file sync process, ex Google Drive/OneDrive), etc.

The more recent updates have started dropping/changing support for legacy GPUs... You'd need to research if this impacts you. Check current and previous OBS Studio logs (pre updates) and make sure GPU support,

Don't ignore the warning about NOT recording to MP4 [which is there for a REALLY good reason[ ... I don't help those that do (or further in your case) ... auto remux if need be.
We still need a log from a Streaming and/or Recording session, that is at least 15 seconds long, preferably a little longer...
