Dolphin drag and drop to thunderbird or firefox

Good day,
after the last update of kde neon plasma 6 when i try to drag and drop the file from the dolphin to the thunderbird attachment after the first file dropped i can not insert the new one the system seems locked.

If I understand correctly, after a drag and drop from dolphin to thunderbird, a second one will provoke a freeze.
May I ask what is freezed? Thunderbird? dolphin ? Or Plasma?

Can you report a bug to Log in to KDE Bugtracking System

no freeze but you are unable to drop the new file into thunderbird window

The same happen to me. I’m not able to drag and drop a file (as an attachment) when I compose a new email. What I should do is “click” on the “clip” icon to open the “add an attachment” dialogue window. I’m using Plasma version 6.0.3 (Wayland) and Thunderbird version 115.9.0 (64 bits)
