Launcher not working....

[Cardellino]

Hello, since the update on December 19, 2022, the launcher no longer works.
Does anybody have the same Problem? If yes, how can I fix it.
Thanks in advance

I'm using deepin-wm and it works fine on my side, are you using deepin-kwin? If you are, it might related to #2613 (comment) I guess?

[Cardellino]

I also use deepin-wm.
When I uninstall deepin-wm and install deepin-kwin the launcher stops responding.
So back to deepin-wm.
I didn't have the problems before the update of 12/19/2022.
Multitasking works but the launcher flickers and doesn't stay open.

Hello Blumia, on this link #2604 is the error of a user who describes exactly the same error with the launcher..
I found these errors in .cache/deepin/dde-launcher/dde-launcher.log:

[BLumia]

The QPixmap::scaled: Pixmap is a null pixmap warning is probably not the source issue of this problem. deepin (distro) should works fine and this issue currently only happens under non-deepin distro, so it's a porting issue.

Currently DDE projects are moving to v23 codebase so we are trying to ensure the codebase migration goes smoothly before looking into other issues, we'll look into this later.

Ok Blumia...
Then we wait for the problem to be fixed.
Here as info if you start the launcher from the console:
