The Unborn Lich - Can't socket support Gems

There is another post for this back from late 2025 but I wanted to make a fresh one.

Just got my Scattering Calamity Titan to level 90 so I could swap to my new Unborn Lich staff for level 90 with 5 sockets.

When I put it on in both Scattering Calamity and Feast of Flesh it says support can't be socketed into this skill... even though I was using them with my level 78 staff.

Any fixes for this... because to even buy another one of the same quality right now it's nearly 5000 divs. I even put my level 78 back and the support gems go back in.

I've tried the online potential fixes and even tried crafting supports from my stash but still won't work. Pretty annoying and expensive bug .
