Avast Free Automatic Shutdown not working after the update

I’ve been using Avast free for more than 2 years now and I’m considering to upgrade I really love the the feature where I the program will shutdown my PC automatically after scanning.But, after updating the software I just noticed that even if I have the “Shutdown the system after the scan finishes” checked my pc will not shutdown. I will receive the notification that it will turn off my PC after 60 seconds but then after the 60-second period expires, it will not shutdown. On top of that, it will not allow my computer to go sleep mode which greatly concerns me. I usually start a schedule scan before I go to sleep so that the scanning process will not interfere with what I am doing on my PC.Since that feature is not working I cannot to use my PC immediately when I woke up because of the chances that it may overheat since it is on the entire night. Is there a way for fix this? Thanks

Might be a bug, wait for one of the devs and/or submit a ticket: https://support.avast.com/support/tickets/new

Perhaps the most important information is missing…
What exact version of avast ?
