StreamFab v6.1.4.9: Constant Crashes

jpp72

This started happening yesterday and i can't figure out why. Seems also only happening on that specific machine. I will try to completely uninstall and reinstall and see if that fixes it.

Here are the logs the 5 times it crashed yesterday before i gave up. It happens while browsing, adding to the queue and downloading:

Did you happen to install another program that uses Qt recently? I didn't see any changes to StreamFab's Qt files themselves recently but I'll double check.

Please refer to the .docx file and feedback, thanks.

Jack,
Obviously we can't read the attachment but I did a little research on my own. Do a search on your computer for all your qt5core.dll files. StreamFab uses version 5.12.12.0. Look for a program that uses a 5.12.4.0 version. That's your troublemaker. You probably have the program in your Path. It's probably a recently added or updated program. Depending on how bad you need the program you'll have to do something, delete it, go back a version, or don't run it at the same time as SF.

Sigh...

Once again, the fact that StreamFab uses very old versions comes back to bite us in the ass.

I am not running anything at the same time as StreamFab except of course a VPN. Since this has just started happening and it technically is running, i believe the issue comes from OneDrive. It was updated November 13th:

StreamFab use v5.12.4.0 and OneDrive uses 5.15.3.0

I will try to exit from OneDrive and see if that fixes it as i don't want to uninstall it.

I think you found the culprit in OneDrive but I'm concerned that your qt5core isn't showing 5.12.12.0 like mine does and what your error says. The (version 0x50c0c) in your error is 5.12.12.0. I almost had to look it up on my IBM 360 Green Card. :p Only another old-timer geek would know what I'm talking about. Ahhh, EBCDIC and Hex, those were the days.

Note: I haven't installed 6.1.5.0 yet so maybe they backed off on the Qt version? I haven't personally modified anything having to do with Qt so even the date matches the 6.1.4.9 release.

I disabled OneDrive, problem persisted.

I uninstalled OneDrive, problem persisted.

Uninstalled StreamFab, re-installed 6.1.4.9 and now Qt is 5.12.12.0, Problem fixed

Installed 6.1.5.0 and Qt is the same 5.12.12.0

Dunno how that happened as i always use the offline installer. Maybe it was something when i was trying to run multiple versions on the same machine. I have stopped doing that but maybe i didn't clean it as well as i thought

Well, all that matters is that it got fixed. Glad to hear it all worked out.
