After applying the Security patches for May 2026, our DRA server broke and stopped working. We are running Windows server 2022, D365F&O .46, and the latest DRA agent and after the patch was applied, DRA stopped working. We were getting an error about the splwow64.exe and not being able to connect. (see below).
We tried uninstalling and re-installing the DRA service followed by reboots, but that did not work. We also uninstalled DRA and deleted the user profile that we set it up with, and then logged back in and installed\configured the DRA again, but the jobs all still failed.
Finally, we started removing Windows updates one at a time, rebooted, and tried jobs until the jobs started printing again. After we uninstalled KB5087424 and rebooted, the DRA service started working again. Not sure if anyone else has run into this but hopefully this helps anyone else running into this issue.
