Db.LayerStateManager.saveLayerState() causes Zwcad to crash

[gswifort]

Am I using this correctly?
Layer states aren't being saved, and upon restart, Zwcad reports a crash during the previous run.

import secrets
from pyrx import Db, command

@command
def doit():
    db = Db.curDb()
    name = _save_layer_state(db)
    print(f"Saved layer state with name {name}")

def _save_layer_state(db: Db.Database) -> str:
    state_name = f"temp_state_{secrets.token_hex(2)}"
    Db.LayerStateManager(db).saveLayerState(state_name, Db.LayerStateMask.kNone)
    return state_name

Works on all platforms but ZwCAD, however this seems to work

def _save_layer_state(db: Db.Database) -> str:
    state_name = f"temp_state_{secrets.token_hex(2)}"
    man = db.getLayerStateManager()
    man.saveLayerState(state_name, Db.LayerStateMask.kNone)
    return state_name
