Problem with vstSound file

How can explain me:
When start cubase 10.5 i have got a message:
VST Sound Library “” not found:
C:\Program Files\Steinberg\Cubase 10.5\VST Sound\FCP_SMT_005_Cubase.vstsound

but, as you can see,
this file is in this path. (have a look at files attachent)

i tried to reinstall but nothing…
