you may want to test the Web-Version of Webex(-Teams) at: web.webex.com
If the Web-Inteface shows the same issue, the issue may be somehow related to your Webex-Account.
Else I think the issue is caused by something on the Computer.
You may consider using this removal tool before you try to re-install the software:

one more idea, since your Screenshot shows a german Interface:
about 1 year ago I experienced the following:
The User-Interface of my Webex-Teams-Setup became more and more a language-mix of English and German.
I finally un-installed the software and ran the most recent installer available at that time.
Result:
Webex-Teams installed in english - on my german Windows (set to "German-Austria").
Very likely because the Installer did not check for the Language-Codes other than "German-Germany" and
ignored all other 4 "flavours" of german (Austria, Switzerland, Liechtenstein and Luxemburg - most recent LCID-Lists of Microsoft even list Versions for Belguim and Italy ).
As soon as I changed my language-settings to German-Germany, the software installed properly.
I reported this issue to the TAC-team back then, but perhaps, just perhaps, the installer still suffers from some weaknesses?
You may try to set your language Config to German-Germany before re-installing the Software again.
just to make sure..
(Note: changing the location-settings may also have impact on other parameters like the Display-Format of Date, Time, Currency etc.)
