"The disk wasn't rejected because one or more programs may be using it"

I bought an SSD and it works an absolute dream on my windows devices but my apple devices have been a fricking nightmare. Constant problems (yes it is formatted correctly etc). The latest being this error message that won't let me eject my SSD.

"The disk wasn't rejected because one or more programs may be using it"

There are no programs!!!! I even followed chat gpts advice and went to activity monitor and tried deleting the "mdwrite" or whatever they are things. I pressed shut down and they didn't!

Someone please help, I don't have the time for this 😭😡
