Same as dagobert... brutal is an understatement, you are left empty handed after the very first digit you enter.
No way -for me that is- to find any logical step
sure some cells are reduced to less than a handfull of options but that's it... every cell can hold an inert five soo it's placement over value really.
and I could not see it..
Feels like there's a constraint missing or something.
Unless that's meant to be a brute force solve... then alright, not my cup'o'tea

This was brutally hard for me. Multiple tries, I had to bifurcate a lot, and some of the logic still escapes me.
