The virtual Hard Disk 1 has wrong access permissions or is used with another virtual machine

Immediately after applying the most recent Parallels 16 Desktop upgrade, I now get the following error when trying to start my VM: "The virtual Hard Disk 1 has wrong access permissions or is used with another virtual machine" error after upgrading to Parallels Desktop 16.5.1 (50696) M1.

I suspect this occurred because neither I nor the Parallels upgrade installer were vigilant enough to shut down my Windows VM before applying the update. I opened a support ticket and have been waiting for four days with no response Parallels Support. I also searched this forum, but not sure if those answers are relevant. Does anyone here have any suggestions?

I've already read and tried the solutions outlined in https://kb.parallels.com/124779 but none of them helped. Scenario 1: The PVM file was not locked. Scenario 2: I am the only user of this VM and only user of the host computer. Scenario 3: I reapplied the permissions in Terminal as specified, but this did not fix the problem.

History: This VM has been running without any problems for a couple of months now. It was fine until I upgraded to the latest version of Parallels two days ago.

Details:
Host: Mac mini (M1, 2020)
OS: macOS 11.4
Parallels: 16.5.1
PVM file location: Stored on an external TB3 SSD.
VM: Windows 11 ARM (upgraded from Windows 10 a couple weeks ago)
 
Hello Maria. It's great to finally hear from support. The good news is my issue was just resolved by Bhaegava (case: Parallels #2998782). He referred me to knowledge base article: https://kb.parallels.com/122983. For some reason, I was unable to find this article in my initial search efforts.
 
Hi, I just upgraded to Windows 11 from 10 after upgrading my desktop to the new M3 chip. I am getting the same error. The system is generally running erratically. When this happened, I wanted to increase disk space to 512GB from 256 GB. Please advise.
 
Thanks for the reply, BradleyT5, but going to that archive.org page just leads me to a page that says "This article is outdated." I tried a couple browsers, but couldn't actually see the contents of the originally post. Regardless--for anybody else trying to solve this problem--I eventually found these instructions somewhere, which did fix this very annoying problem.
To share the virtual machine with all users, type the following command:
sudo chmod -R og+rwx /path_to_virtual machine_bundle
