Dreamweaver CC 2019 lags and freezes

Hi, for some weeks, I have lags and freezes. They may last 30 seconds and during this time i can't touch the code. I discovered that the processus "adobe dreameaver CC 2019 helper" is involved, if I kill it ( they may be several of it, I just have to kill the one who take the more processor time), lags go away. Has  anybody have a better solution than this one ? Maybe an explanation about it.

Thanks

Gilles
