Editor crashes while making script only build if regular build was cancelled before. Refer the attached video

Steps to reproduce:
1) Create new project
2) File > Build settings > Build > Cancel once the build starts
3) File > Build settings > Check development build > Check script only build
4) Make a build on the same path
5) In the copying file failed dialogue box > Press Cancel

Actual result: Editor crashes
Expected result: Copying file failed dialogue box should close.

Reproducible in: 2019.1.0a13, 2018.3.1f1, 2018.3.0a1
Working fine in: 2018.2.18f1

Note:
- Editor log has been manually attached
- Scripts only build, makes a build only for the changes made in scripts. It needs to be built after a regular build and at the same location.
