The Pl@ntNet app is actually pretty good at identifying a lot of different plants by snapping a picture on your phone. https://plantnet.org/

The light green serrated leaves in the middle are a hackberry tree that was planted by a bird. They have a bad reputation, but they’re fast growing, native, and provide decent shade. If this is at least twenty feet from your house, you could let it grow and have a tree there instead of a mystery shrub.

You can confirm it’s hackberry by looking at the veins at the underside of a leaf. You should see three main veins starting at the base of the leaf, similar to if you held up your three middle fingers.

PictureThis says it’s a Japanese euonymus

Definitely fixable it’s just been “neglected” a bit. You’re probably looking at a Euonymus and those barely require any upkeep to keep alive once established but will grow wild and make funky shapes. Definitely want to do more research on which specific type it is but it’ll probably come down to you waiting until the later autumn being in Texas and basically chopping it to the ground. From there it’ll bounce back with new fresh growth and you just pay attention in pruning it so it stays within your desired shape
