Description of problem:

If there is a vlan device configured in kickstart that should be activated in installer, and whose IP configuration fails there is a chance that under certain conditions (race) the installation will crash.

Observed with kickstart test:
https://github.com/rhinstaller/kickstart-tests/blob/master/vlan-httpks.ks.in

Version-Release number of selected component (if applicable):

RHEL-8.2.0-20200212.n.0
anaconda-29.19.2.13-1.el8.x86_64.rpm 

How reproducible:

In our kickstart tests (using boot.iso) always.
Trying to reproduce in VM I didn't succeed.

Steps to Reproduce:

I can only add our kickstart tests configuration as hints for reproduction:
