Two saves corrupted by Nomad Spire

Twice now ive put dozens of hours into a world, went to unlock the nomad spire, and got stuck in an infinite loading screen. Load into my safty altar on save load and get the same infinite load screen. Tried loading the saves with different characters too. Already verified files 3 times, updated drivers and restarted my PC. Think im done with this game now just lost all motivation to start a third f*cking time

Edit: recovered the second save, managed to load into the saftey altar at the bottom i made, just took a while. First save ill try again with later but that ones been bricked for days
