2024 Husqvaena TC125 front end shaking 5th gear and in the air.

My 2024 Husqvarna TC125 has had an issue with the front end for the last 2-3 weeks. We have done everything we could think of and it is stemming from the front end of the bike. We trued the front wheel and took it to a dealership to check the tire tube and make sure it was true. They said it was one of the truest wheels that has come into the shop and that it's not coming from the front rim. I only feel it on the ground when I'm going low 5th and when I go mid to high 5th it gets way worse. The bike has had 1 top end done and it has a little less than 48hrs. My right front fork seal tore at 35hrs and we had it fixed. We bought the bike new a few months ago and need to get it fixed as it is causing a stop to my practices each time.
