Hi folks. Please make sure that there is not a third party app interrupting ProSeries functionality, this could be an anti-virus or printer drive app. Try disabling the third party app, updating your software, and then turning the third party app back on. See the ProSeries article Troubleshooting Server Busy, or This Action could not be completed errors in ProSeries. From the Microsoft community see How to temporarily disable antivirus and firewall. Let me know of any updates in the replies below.
