Unable to run 32-bit exe in windows containers

I’m trying to build a docker image (using mcr.microsoft.com/dotnet/framework/runtime) which executes a – 32-bit – MSi installer silently to install an app. While this had been working in the recent past on the host VM (windows Server 2019), it has stopped working all of a sudden. The problem seems to be related with a newer windows update or security patch.

Worked on v17763.678
Doesn’t work on v17763.737 or later.

Does anyone know of any recent changes related to this that restricts running 32-bit apps in windows containers?
