workaround: returning to Nextcloud-3.8.2-x64.msi with deinstall and install solves the problem

Same here with Linux client on Debian testing (see https://bugs.debian.org/1054172 )

Problem seems to be solved (3.11). Now the main menu color is not black but not the "nextcloud- blue". It has the "color of my provider" t-online. Which is OK.
