Investigation Status:

The contract succesfully passes the __validate__ entrypoint, returning VALID, executes the first approve call, but fails when calling the multi_route_swap function.
The CallEntryPoint created to execute the multi_route_swap is the same when executing with native and vm, inculding the called contract's address, selector and calldata (and these match the network data too).
Contracts with signatures similar to the multi_route_swap have been tested to work properly with standalone native. I also did a quick test with passing large nested arrays and those worked fine too.
