I've been battling with the same thing with a 1TB SanDisk Extreme SSD. I did some experimenting and this is what I've found (I'm on a M1 MacBook Pro btw)... If I go USB C > USB C (either using the Apple cable that comes with the charger or 3rd party) then I get the kind of issues that others are reporting here. I'm pretty certain it never caused me an issue till after updating to 11.2 or 3, but anyway. If I plug in a USB C breakout cable to my Mac - the kind that gives you multiple USB A, HDMI, Micro SD ports etc, plug the drive into that going USB C > USB A. It works just like it always did. Not sure why it makes any difference, but in my case it does.
