Starting Point psexec

For some reason psexec gets stuck at uploading the file (same thing as here, so I tried to use, which worked, but I somehow screw up and my vm froze, so I had to restart. When I tried to get the shell again with administrator@ it asks for the password, so I provide it and then it crashes with:
[-] SMB SessionError: STATUS_SHARING_VIOLATION(A file cannot be opened because the share access flags are incompatible.)

Did I screw up somewhere or is the machine broken or what. Because according to the tutorial, psexec should work just fine. I thought I’d wait a day, so that the machine would reset. Didn’t help tho…
