@amckenzie I searched for Qt5Core.dll crashes and I found this topic where OneDrive was the culprit: SOLVED:DVDFab10 x64 crashes on startup due to error with Qt5core.dll module. - DVDFab Community

Don’t worry - I have reinstalled CC5 on the other copy of Windows 11 on my Workstation and it’s working fine.

I haven’t noticed it with IC or CC, but the latest NVidia drivers (591.x) break the rendering in some apps. I still use an older version of Vegas Pro and I had too revert to the previous driver (581.x).

I have the same problem!

Any updates on this subject? Have the same problem: splash screen - initializing… and disappears.

If anyone is continuing to receive crashes, or are unable to launch CC5, please contact Technical Support using the form HERE. They will try to help you resolve the problem. Thanks.

After the latest update, I can only start CC5 as an administrator.

Aha, I hadn’t thought of running as administrator - CC5 now launches fine. Thanks for the tip @grenz-claudia

Another option
Reset CC5 to version 5.04 in the RL Hub
Wait for a new update

Same!! but if I open iClone 8 then open CC5, it works!! then I close iC8 and all good!! Weird!!
