We tried adding the -high-effort flag but got the same results

How long does it take from when you run the command until you receive the error? If it takes more than an hour, then your kernel is likely too complex for the compiler to process. The "-high-effort" is for placement and routing and will not affect your case; your kernel compilation is failing in the OpenCL to HDL conversion step, not placement and routing.

    Then try reducing your design complexity. You can also test 19.3 to see if the same problem will still occur.
