ZKVM-377 [BUG] Arkworks not compatible with Risc-0

You issue seems to be related to the crate ahash not having access to getrandom in the guest. You have, at least, two options:

1. enable the getrandom feature on the risc0-zkvm crate
2. Add something like this to your guest dependencies: ahash = { version = "=0.8.6", default-features = false, features = ["compile-time-rng"] }

The first option will expose a getrandom implementation that uses the sys_random ecall, i.e., your guest will get randomness from the host.
The second option will generate random numbers at compile time and embed them in the binary.

Fixed: I used the second method and it works. Thank you
