Sage 2020 Locking Users Out

Has anyone else had the issue of Sage 2020 running the the processes and details in task manager but not showing the interface and then locking the PT.LCK file and SUA00021.LCK file on their server? Every morning this happens with our Sage 50 and we have about 20-25 constant users daily. Support hasn't been able to resolve the issue and I'm looking for anyone that can help out.
