Ctrl C or V not working constantly with Grid View in SharePoint List

Recently - I'm no longer use Copy&Paste short cuts ...on SharePoint List while in Grid View editing

I experience this randomly,  on many Lists and web browsers 

I have noticed this since introducing new features, such as opening the List Webview App, adding a New built-in Form ....etc. 

I never had any similar issues in the past 3 years 

P.S. Dont suggest switching to classic view, the switch is not working at all 🙂 !
