Only a couple of things I can see that MAY be causing
the issue, but guesses only.

Detail Faces is set to off, instead of auto.

Narrow Hull Offsets is set to standard 32. If your walls are thinner
than 32 this it may cause problems.

Otherwise, is there any way to send me the level?

I was having the same issue with the newest 7.7 build of 3DGS. Turns out I had some shaded surfaces in my mostly "flat" surface level. As soon as I changed those to flat, the compiler was able to get to, through and past the "tessellating surfaces" stage no problem. I'm guessing that the shaded surfaces I did have were too large.
