Model missing texture in a spot

I have made a 3D-model of a small village, it’s flown with a Mavic 3 E RTK and the number of photos is 2412.
In one spot the texture is not there, it’s only showing un-textured ground.
Is it possible to fix that without re-rendering the whole model?

Hello Per,
those triangles seems to be too big. Have you deleted and filled that part or have you provided any modification of it?
Can you try to set Large triangle removal threshold under Unwrap settings to a bigger value (like 1000) and unwrap and texture your model again?
Or if you still have the original model, you can texture that and then reproject texture to this one.
