Bias FX 2 disappears in Studio one 4 Prod

  • Hi everybody,

    This my problem: Bias FX 2 worked fine on my computer (windows 10 family ) but after a update of studio one 4, the plug-in disappears for the plug-ins list.

    I reset the the plug-ins black-list
    I checked the location of the vst plug-ins
    I reinstalled Studio One 4 and the lastest Bias FX 2
    But I cannot still see Bias FX 2 !!

    Does somebody face the same problem and have a solution ?

    Thanks in advance
