Dirtbike engine not starting, has fuel air and spark. 2024 CRF250F

Hey all! TLDR I got it stuck in mud and now the bike doesnt want to start. https://www.reddit.com/r/Dirtbikes/s/2THxclv6MU

After getting back home, I cleaned the bike thoroughly, including deep cleaning the airbox and reoiling the air filter. The bike wouldnt start. I then removed the exhaust and cleaned the mud out of it aswell, and noticed the bike started up easily when the exhaust was removed. After installing the exhaust back on, it wouldnt start again. The exhaust isnt blocked as I made sure to clean it out well.

I then removed the spark plug, cleared the cylinder just to be safe and cleaned the plug and checked for spark, its definitely getting spark. Also getting fuel, if I crank the throttle while holding the ignition down I can see excess fuel coming out of the exhaust. Ideas? I might buy a compression tester to be sure.

The bike didnt suck in water, It was running the night it got stuck and when I left it to come back the next day I left the engine well above the water line. Thanks in advance. Let me know if you need more info.

EDIT, SOLVED!: It was a broken ground connector! Ill make a comment with the picture. Im so happy it was an easy fix.

(Update) Biggest mistake of my career

Success! We got it out. Bike turned over fine but wouldnt start. My guess is the air filter is soaked. Winch worked great, towed the bike back with me riding it, it went well. OverallcId rate the experience a 5/10. Couldve been worse!

Biggest mistake of my career

Going to come back tomorrow with the quad to winch, its stuck good. I think im going to deep clean all the bearings and seals. We got the front end up and the engine is no longer submerged so I think the engine will be fine.

The mud looked fine at first but I read it wrong. Its all soup. Lesson learned. I should really stop sending it lol

Apologies for the image quality, was very hard to get them sharp in motion. I really like the black ones with the orange heads, its interesting because these all come from koi pattern females and grey with black stripe males so its cool to see the different patterns.
