telegram-desktop: symbol lookup error

Hello, I recently (probably) updated telegram-desktop and now it wouldn't launch:

telegram-desktop: symbol lookup error: telegram-desktop: undefined symbol: _ZNK12QCommonStyle11drawControlEN6QStyle14ControlElementEPK12QStyleOptionP8QPainterPK7QWidget, version Qt_6

Reinstalled several times with the same result.

telegram-desktop-bin from the aur is ok.

Re: telegram-desktop: symbol lookup error

It seems to be a problem with qt6.5.
After I disabled the kde-unstable repo then downgraded all qt6 packages telegram-desktop now works fine.
