--vpi-trace=results/counter_tb_vpi.log
Could you provide this log?
Also, try running with COCOTB_LOG_LEVEL=TRACE to get more information about what is happening internal to cocotb's shared libraries.

The above was already ran with COCOTB_LOG_LEVEL = TRACE. Also the log file is completely empty.

You could try setting COCOTB_ATTACH and connecting with a debugger. It stops and waits for attach right before the log
-.--ns INFO gpi ../gpi/GpiCommon.cpp:101 in gpi_print_registered_impl VPI registered
The very next thing should be registering for the VPI startup callback using cbStartOfSimulation.

Somehow the value of Rng.I32.Dir in grt-rtis_utils.adb:293 is a number instead of dir_downto. How can I track this back to the rtl parsing? Not at all familiar with the internals of ghdl

Found out this occurs because I had --wave in my SIM_ARGS instead of --vcd as custom types do not work with the VPI interface to cocotb.
