Lightroom v9.1 Launch Error

Question

I am encountering a persistent issue with Lightroom Desktop (v9.1) on Windows 11. The app fails to launch and displays two error messages: "invalid capture index" and "can only init the Organize Module once."

System Info:

OS: Windows 11 (fully updated)
Version: Lightroom v9.1

What I have tried so far:

Restarted my PC and checked Task Manager (no duplicate processes found).
Attempted to reset preferences using the Alt+Shift shortcut.
Performed a clean uninstall and reinstalled the app through Creative Cloud.
Checked AppData folders, but the issue remains.

Hi @614_%8450

Thank you for reaching out. I appreciate your patience with this issue. Could you please confirm when this problem began? Have there been any recent changes to your system, such as the installation of new antivirus software, web extensions, product updates, or operating system updates? Was version 9.1 functioning correctly before this issue arose?

Regards,

Srishti
