Character doesn't show up in Anim BP

I’m a beginner. I’ve been following a tutorial on youtube and have been doing well! However, I had the great idea to import a character and I chose an option that restructured the skeleton. It broke everything! I since, deleted that character and reimported the animations that were broken and now there’s no character in the AnimBP preview and my character only moves in T-Pose.

Any Ideas? I’ve been trying to figure this out for two days and i’m losing my mind!
