if you don't need flicker removal, you can ignore the exposure, gamma clamp, and text layer.

If the white balance is not affecting the image or not well enough, you may have a hue issue which is currently not directly supported.
You'd have to precomp the 'exposure repair' comp to get the hues to align to the 2D correction of magenta versus cyan in a vectorscope.

Additionally, your white balance problems maybe so destroyed that there is no data left to recover(I'm only guessing here).

You can use premiere or resolve and use the HSL vectorscope to get the image centered so perceptually it looks balanced. Then you'd cut various offending spots of your clip into smaller sections, fix them, then transition from clip to clip with a dissolve. This may be more accurate and faster if your clips aren't fluctuating every single frame.

If you have no color data in one of the channels, you can also try using the channel mixer to borrow color data from another channel.

Again, it's hard to recommend the correct direction you should take without seeing the footage. Also, it is hard to explain how to do advanced color correction in a simple post.
