Face Textures not baking and Hair not rendering in the Strand-Based Hair

I have been dabbling inside MetaHuman since the past week, for Reference I am using Version 5.6.1 and 5.7.4 for trying to crunch out Hyper-Realistic characters.
The bug/ issue/ problem is that the Face texture for LOD0 and LOD1 which I want and have set to 8k and 4k for another character are not baking/ generating I have tried to solve this by doing the following:

  1. Enabling Virtual Textures Lightmap inside the Project settings.

  2. Rebuilding the Rig.

  3. Re-downloading the source textures

  4. Enabling all other ChatGPT recommended settings that are related to Virtual Texture.

  5. I have also run these commands “r.Streaming.PoolSize 4000” to solve the GPU caching issue.

  6. Although I want all the textures in 8k… I even reduced the resolution to 4k inside the assemble menu.
    The Hair rendering is also being an issue.
    They do not render in the Strand Based setup which normally offers the best output from metahuman.
    PN: I cannot ‘settle’ for a lower quality.. So I request you to not suggest to '“lower the quality” or “convert to haircards”
    Also, In the screen shots I have attached below, I lowered the Texture to 2k just to get some output at LOD0
    One more thing to note I have used the Preset ‘Walter’ to test if the issue was with customization. So the Old man with longer hair is Walter

    The image below is a personal Customized character. (I do not know why the stats suggest the textures to be 2k but believe me I have Assembled the character while keeping everything at 8k once and 4k once) and also please look at how the hair renders in both the images
