MSE needs to be downgraded
I found out from the TAC that it will be done in the same way as the upgrade.
completed post install scripts in progress No longer progressed in the corresponding phrase.
It was downgraded to 8.0.150.0 -> 8.0.140.0
I canceled and reinstalled it to 8.0.150.0 and tried again, but it stopped the same in the same place and didn't go any further.
The integrity check is confirmed to be normal.
Does anyone know or experience the issue?
