    I am experiencing the same exception (System.InvalidOperationException - DragDrop registration did not succeed). This has been consistent through all LinqPad 7 beta releases. Occurs on both Windows 10 and Windows 11. Occasionally will progress through to open the application. I have not experienced this exception on LinqPad 6 or previous.

    Happens to me as well, Windows 10. Hope it gets sorted soon.

    Can you please try the 7.1.3 beta - this generates more diagnostic information.

    After running, please post the latest entries in %localappdata%\linqpad\logs.linqpad7\log.txt

    Thanks!

    Try starting LINQPad with the -tt switch and let me know if it fixes the problem

    LINQPad7-x64 -tt

    Yes. By starting the application with the -tt switch, it no longer crashes.

    Thanks, everyone.

    This should now be permanently resolved in 7.1.4.

    When do you expect 7.1.4 to be out (not the beta)?

    If there are no further issues, I'll push 7.1.4 to RTM tomorrow or Friday.
