I tried on Windows 10 and Laz 2.0.0 / fpc 3.0.4 and confirm an Access Violation following the steps given. Doing the same with Lazarus trunk or Laz 2.0.2, however, does not yield this error.
So, before wasting your time with a duplicate bug report, I'd recommend to install the new Laz 2.0.2 and try again, this will be a good idea, anyway.
