Blade Cursor dissapears within Adobe Premiere on M1 Max...only shows regular mouse cursor...

Did you try it with a new project. Start one, and drop in a clip, preferably one that you haven't dropped in ever before. Let us know.

I understand the frustration, but ... you don't give nearly enough information to understand exactly what is happening under what circumstances.Without that information, the post is simply venting. Which is at times a feel good thing, true ... but doesn't help solve a problem.

So the question I have, is are you specifically talking about when you hit the C key to change to the Razor tool?
