Saturn 3 Ultra - Hanging after file upload.

[Vmess34]

The file upload works just fine. It is available on the printer, and I can force exit with ctrl+C and run the print command with no issue. We just get a hang with no messaging. Happens on any .goo file, any size. My attempts range from ~14MB to ~500MB. I can give the full --debug output if its needed, but for now this is the end of it, which does correctly show the transition of states:

on 168490728: 16:52:46,728 DEBUG: STATUS: {'CurrentStatus': 2, 'PreviousStatus': 0, 'PrintInfo': {'Status': 0, 'CurrentLayer': 0, 'TotalLayer': 0, 'CurrentTicks': 0, 'TotalTicks': 0, 'ErrorNumber': 0, 'Filename': ''}, 'FileTransferInfo': {'Status': 0, 'DownloadOffset': 175320953, 'CheckOffset': 0, 'FileTotalSize': 175320953, 'Filename': 'local.goo'}}

Afterward, console just sits until ctrl+C or other interrupt is sent, where I'm met with the following exception:

Afterward, everything is on the printer as expected, and can be run as normal.

During file upload on Mars 4 Ultra I'm getting a similar hang up after the file transfer is "100%" (albeit with different traceback asyncio errors). However, after cntl+C interrupt I cannot get the print to run.

ioc % ./cassini.py print test.goo 
12:56:11,666 INFO: Printer: Mars 4 Ultra (ELEGOO Mars 4 Ultra) (192.168.1.36)
12:56:23,116 WARNING: Too many status replies without success or failure
12:56:23,116 ERROR: Failed to start print

Question about cassini basic functionality: When a goo file gets successfully uploaded does it actually show up on the printer as a local file (i.e. accessible and could be manually printed from the printer)? Because in my case that's not happening.
