Start with salt/modules/win_timezone.py around get_offset and the bundled zoneinfo implementation shown in the traceback. Reproduce salt '*' timezone.get_offset with the reported Asia/Vladivostok timezone, then determine why tzdata is unavailable in this installation. Done means the command returns the correct offset without the exception or fallback warning.
