(Win) Lightroom Classic It's flawed

Hey, @Gábor306177892yhi. Welcome to the Lightroom Classic Community. I'll need more info to help you figure this out. Please share the version of Lightroom & operating system you are working on? Do you see an error or pop-up in-app or while using any tool? Please share more details, like screenshots or video recordings of what you see.

For now, try the basic troubleshooting steps from this content: https://helpx.adobe.com/lightroom-classic/kb/lightroom-basic-troubleshooting-fix-most-issues.html

Awaiting your response. Thanks!
