ERROR: VAE is invalid: None

If the VAE is from a checkpoint loader node your checkpoint does not contain a valid VAE.

You need to update KJNodes, to the latest version
after that all should be good ;-)

Thanks now I get this issue:

Says error in the Video Vae
But your model loader screenshot shows the main model, so that one is probably fine.
The error comes from the Vae loader (video vae) it seems.

Yeah I am using the vae from here: https://huggingface.co/Kijai/LTX2.3_comfy/tree/main/vae

Yes but i mean the vae loader (the node). You need the very latest of KJNodes to load the LTX vae files
Try update KJNodes, think that should fix it ;-)

I updated it to the latest however still getting the same error, these are my models and vae layout

So strange. that looks all correct.

Where did you download that video vae from? Although that looks like from Kijai split files, so thats also correct

Maybe try re-download that vae, I cant see anything wrong in your setup.
The only "unknown" would be the GGUF file, but if the GGUF file was incompatible it should throw the error at the Unet Loader.

Could you also look under the VAE loader (move it to the side), and see if its connected to a small "Set Node".
