after update KDE plasma panels became black and window bar and widgets disappeared

on my laptop TUXEDO InfinityBook Pro running leap 15.4 and KDE argon, after the update to (I suppose) KDE Plasma 5.26.4 (the one with Dolphin Version 22.11.90) the panels are black (probably dark style with silver letters) pratically unusable, the window bar (the one with the little icons to close minimize and maximise on the top of windows) disappeared and it is not possible to move windows, all the widgets and the settings disappeared and many other issues.
how can I have at least the white panels with black letters and a working and usable plasma or to reset plasma to a default condition?

As far as I can see, LEAP 15.4 has Dolphin 21.12.3 and KDE 5.24.4.

Then I assume you have your stuff from something different then the standard repos. Your remark "after the update to (I suppose) " then looks to me as if you do not really know what you are doing.

Better find out first and tell here where you have your KDE from.

Hi hcvv, manythanks, my I suppose was becouse I don’t know where to check the plasma version and also in a nearly unusable plasma, I said the dolphin version becouse has been the one that is easily checkable opening dolphin and check it in help.
As I said in my post I’m using KDE Argon from here and setting the repositories as described here summing up these:

Note for openSUSE Leap users: Leap ships with a Qt LTS release, which is not recent enough for the newest Plasma. So to use KDE:Frameworks5, KDE:Qt5 is required. Some applications from third-party repos might not be installable as they require the specific version of Qt shipped with Leap.Version: Leap 15.4

Thanks for the explanation. I suggest that it is better when you in the future make it more clear in your first post about a problem, that you are running software outside the normal released version. Stressing such deviations is very important to get people on the right track when they try to help you.

Try

Alt-F3

on your keyboard
Then if you are using x11 run

kwin_x11 --replace

If you are using wayland run

kwin_wayland --replace

Could be the windowmanager failed.

Hi conram, I tried bu no succeed. these are results:

Alt-F3

nothing happen

kwin_x11 --replace
pla@pla4-TW:~> kwin_x11 --replace
kwin_x11: symbol lookup error: /usr/lib64/libkwin.so.5: undefined symbol: drmModeFormatModifierBlobIterNext

Hi, here is the first 15 repos, I did in two parts becouse susepaste tells me that I’m a spammer and doesn’t allow me to create a text file:

Hi
Honestly with that amount of repositories, your better off running Tumbleweed… if your going to run Leap, then treat it as Leap…?

I think with TW or LEAP, nobody here will have the slightest idea what exactly creates the problem mentioned in the title. People will only wonder that anything goes.

manythanks for the suggestio malcolm, I tried tumbleweed but it was too much unstable for me, so I stepped back to opensuse Argon
anyway the problem seems solved, triggered by arvidjaar I thought that could be a version or something of this conflict, so in yast>software management I switched system packages to the agon and packman repositories and everything goes well now
