Bug description and reproduction

When launching Hydrus via the Bundle (Not CLI) it simply doesn't start, just silently dies. When running via the shell we get the error-messages below. The last known working Version is 504. The hydrus_crash.log pretty much contains the same informations. Let me know if you need anything else.

Log output

I was a bit confused yesterday, sorry for that, running the correct binary shows the issue still persists with v506:

PySide6/__init__.py: Unable to import Shiboken from /Users/xxx/Downloads/Hydrus Network.app/Contents/MacOS, /Users/xxx/Downloads/Hydrus Network.app/Contents/MacOS/lib

I am reopening the issue.

Thank you for this report, and sorry for the trouble. I have been working on the same issue with another macOS user and have updated the client to report more information for this in tomorrow's release. Please try that and let me know what different message you get, if any!

This is an odd one. Not only is it selecting the wrong Qt library to use, the exact line it is throwing an error on is supposed to be after it found a good Qt to use. Furthermore, there's no obvious difference between v505 and v504's built Qt (PySide6).

If you know how to set such things, you might have luck setting this environment variable: QT_API=pyside6

Running 13.0.1 on an Intel Mac.

v507 binary crashes with the same error. Running from source works fine when I select 5 or 6 from the setup_venv.command

[docchaoswizard]

Yep, still crashes. Here are the details:

During handling of the above exception, another exception occurred:

Exception: One of the Qt modules could not be loaded! Error was: No module named 'PyQt5'

Of the different Qts, qtpy selected: PySide2 (not selected), PySide6 (not selected), PyQt5 (selected), PyQt6 (not selected). Here is info on QT_API: No QT_API set.

If you are running from a built release, please let hydev know!

The same happens when i set QT_API=pyside6 (Or any other Qts). My python Version is Python 3.10.8, but that shouldn't matter.

Do you need any more informations? Oh by the way, it doesn't matter if i start the client through Rosetta on Apple Silicon or natively on an Intel Mac.

[KamillaPup]

I'm having the same issue. Shouldn't it make a call to PyQt6?

This is the crash log using 508:

hydrus_crash.log

[KamillaPup]

Here is the crash from the 508 fix hydrus_crash.log

[KamillaPup]

I just want to confirm that 509 fixed this <3

Also Hydrus works great in Ventura.

[docchaoswizard]

v510 works great! Thank you very much :-) I think we can close this.

@KamillaPup Thank you for that information! Now i can upgrade in peace ✌️
