NI vst and vsti very very slow to load

Hello community. I come to you because I have the impression that my vst and vsti Kontakt have become very very slow to load. I put you a wetransfer link giving access to a video in which you can see that unlike my other products which load in just 2-3 seconds, those of NI are very slow to load (Massive, FM8, guitar rig6...). do you expect me to help please? Thank you so much
