Error in .jcall("RJavaTools", "Z", "hasField", .jcast(x, "java/lang/Object"), : java.lang.NullPointerException: Cannot invoke "Object.getClass()" because "<parameter1>" is null

Sorry for raising the same issue again; I read the same issue posted several months ago, but I am experiencing exactly the same when setting up a new environment here in a new machine.

Using pbf directly downloaded from Geofabrik and an official GTFS files from Columbus. No network file created despite outputting "Finished building network.dat at xxx/network.dat". pbf.mapdb and pbf.mapdb.p files are created though.

I tried both the stable version and the dev version, both giving me the same message. But the test data and code works. No idea how it happened. Attaching environment for reference:

Tried Florida and Miami GTFS. Problem persists.
