On 4 differents iMac with Mojave, the assistant migration stop working after the installation of Security Update 2020-005. After the launch of assistant migration, the screen go directly to the login screen.
Others have the same problem?
iMac 27″, macOS 10.12
Seem that the Security Update 2020-005 is broken :(

Definitely broken Migration Assistant.
How Apple left this version out?
Very disappointed

I had a similar experience.
I installed the update and immediately my 21.5" (late 2013) iMac became unusable (beach balling on every mouse click; my Time Machine backup disk showed NO backups had been made; EtreCheck showed MAJOR issues; etc., etc.)
I spent several hours running Apple H/W diagnostics, booted into Recovery Mode and ran Disk Utility on both my Macintosh HD and Time Machine backup disks;. No H/W errors or disk errors were reported.
I then used Recovery Mode to reinstall my last Time Machine backup image just before I installed the last Security Update, and now everything is operating normally again.
I have NO third party S/W installed on my iMac -- I have no idea why this particular update "bricked" my system.
