Tldr: use Mac reformat security level 5 to get that too slow drive working again.
I thought I would share this as it worked for me. I had a lexar USB stick 128gb it worked fine then after a firmware update a while back it would get that too slow error. Well, I reformated and tried, till the error. Then on the Mac, I tried the security reformat, 3. And still it failed, I didn't want to do the level 5 cause that takes hours. In the end I used security reformat level 5 and the USB stick works flawlessly with 2019.36.2.1.
