option to scan package names is on, right ?

?

I have installed texlive on win10 and I can't reproduce the issue. You can check if %appdata%\texstudio contains packageCache.dat , but I have no further ideas. May be a win11 issue but I don't have win11.
packageCache.dat contains only packages that are placed in C:\texlive\texmf-local
% detected .sty and .cls filenames MinionPro MinionPro-FontDef MyriadPro MyriadPro-FontDef asyntax bera beramono berasans beraserif classico europs eurosans fontaxes fourier fourier-orns fourierx frutiger futura gandhi garamondx gillsans literat ltxmdf luximono mathpmnt mdframed mdsymbol optima otfontdef tabfigures uarial ulgothic xagaramon xutopia
Looks like it is enabled.
