FSlogix - local folders hang. Help

Hello community ! I need your help. As you know, in FSlogix there is a problem that sometimes happens, the folder C:\users\local_%username% hangs and stays on the server, the next time you log in, the folder is duplicated. I can't make a request to microsoft and Jason_Parker (MSFT) said he would be willing to help me personally if I could simulate the problem in a lab environment and collect logs, but I'm not able to. Can you help me to discover how this problem is happening ? At the moment I noticed that if the virtual machine is shut down, the profiles that were there at that moment will hang and after powering on those users will have duplicate folders. But I want to understand the scenario how this happens with applications. Maybe we can come up with a solution together.
