Yup,

Lags as in blue circle of death that eventually finishes so not a total crash.  Have looked at video settings and other areas but makes no difference.  Experiencing randomly on all machines which are Win10 or Win 8.  Auto save detail and show input warnings in detail tab are both off.  We use a NAS system on network for storing/sharing client files.  2020 and 2019 are not experiencing this specific problem.
