Trouble shooting

Hello, I started to attempt to stream this week after researching and setting things up. I did a short video and recorded it. Seem to play ok for 2mins. Then i streamed and afterwards i looked at the 2 hour long video and notice that soon as i enter the game the video just freezes and after a min or two jumps ahead to like 2 mins in and stops, the audio seems to keep going without much issue, i need to talk louder is about it there.

My setup is Intel I7 12700 cpu , 64 gigs of ram, SSD hard drive, Radeon RX590 8Gb video card and I am hard wired to my router. My internet speed is like 966MBS and upload 40MBS. I'm streaming 1080 reso

I followed videos for settings. When my daughter watched my stream she said it was laggy but not as bad as the recording and when i look at the recording on twitch its super laggy also. Looked at it on other computers too and same laggy nonsense.

Would love some help if possible with this matter. I did get practice in talking and trying to be more entertaining. When I google this i find the AI grabs my question and turns into response from people having issues just viewing a video on twitch which im not having.
