Baby super excited about starting solids and won't sleep???

We just started our nearly 6m old (a week away) on solids just at dinner and she REFUSES to sleep. Like, she was awake from 11-2:30am and nothing we did could put her to sleep—not nursing, not even contact napping. It was really weird because she had decent naps (not too much, not too little) during the day before.

Typically, she is ready early for her first nap and goes down easy—almost struggles to make it to a 2 hour wake window. Today, she is wide awake 2.5 hours into her first wake window.

Anyone else experience this? Is this normal? I saw a lot of posts about a 6m sleep regression, but I know it's just about hitting milestones. Does her tummy feel funny and she can't sleep?
