After PD18 upgrade, Windows10 VM frozen after waking from sleep

Since upgrading to PD18 a week or so ago, any time I close the lid on my MacBook Pro 16 for more than a few minutes, when I open it again everything is instantly resumed except my Windows10 VM which is completely frozen with the clock indicating a time closer to when I closed the lid on the computer.
Under PD17, occasionally it would behave in a similar manner but after as much as 2 or 3 minutes it would eventually wake up, seem to reset the Windows Explorer processes, and continue. Now it's just frozen - any attempts at intervention do nothing at all, and I can wait at least 15 minutes and still no change. if I suspend and resume the VM, after resuming the screen will be 100% black. Computer is a 2020 MBP 16 with 64 GB RAM, latest OS X. VM is configured for 4 processors and 16GB of memory.
Any suggestions would be greatly appreciated. If I can't fix this PDQ, I'm going to have to try another VM vendor - as an IT/business consultant, losing work and having to kill and restart Windows is totally unacceptable.
 
Am seeing exactly the same behaviour here on a similarly spec'd 2019 model Mac... have just installed the patch to 18.0.1 (53056) - hopefully this addresses these stability issues
 
Same thing post upgrade to 18.0.1.... Super annoying bug - considering downgrading back to V17 as resetting Windows VM after sleep is super annoying

I downgraded back to v17 back in September and it hasnt skipped a beat.... am still running that and have now upgraded to MacOS Ventura - wondering if this issue was a Monterey thing but dont have the time to flip back and forward between Parallels versions in case its not
 
I'm facing the same issue after installing the last version (at this moment) of Parallels Desktop 18 in MacOs Ventura, even this MacBook Pro 16 2019 was reset and completely configured from scratch (no corrupted configuration files or something like that). Every time this happens I have had to reset the Virtual Machine and lose everything I had done. I have changed the Virtual machine optimization settings for full use and medium also, incrementing resources (more than 8GB of RAM, I have 64GB). Resources limits are not reached, I monitored with an activity monitor, so It seems that is an error in the Parallels Desktop version
 
I am on Version 18.1.1 (53328) and in the last week I have had 3 instances on my Imac that after waking the computer the VM is completely frozen as well. Only way I have got back into windows is to Action -> Reset. So far I haven't left my VM with unsaved work but I will only be lucky for so long.
 
Make that a 4th time.. grrr. I know it is going to be frozen when the screen resolution is like old 800x600 when one of the monitors wake up. (not sure if that resolution hint helps). Thanks and happy Friday.
 
The issue of the VM being frozen after Mac resumes from sleep is affecting me on 2 different machines. Very frustrating. I have a support case open and they seem clueless so far.

BenR11 happen to get your case resolved? I forgot to close out my VM last night and found it frozen solid today.
 
After reading through this, and following links to related issues and trying other things that didn't work, I made a change 2 days ago that seems to have stopped the problem for me (Win11 frozen after Mac wakes from sleep). If the problem returns, I'll post another update, but so far, so good. On previous versions of Parallels, when I installed Win11, the startup and shutdown options were set to "Start up and shut down manually" by default, but for whatever reason, installing Win 11 on Parallels V18 defaulted to "Custom". I switched the option back to "Start up and shut down manually", and the problem seems to have stopped. Each time I've woken my mac from sleep since then, windows is still responding normally. This setting in Parallels is found in your VM settings under "Startup and Shutdown".
 
Unfortunately, after a few days, I started to see the issue again. It seemed to help at first. I don't know why, but the problem returned. I've made no changes to any versions or configurations since the last post.
 
I'm getting this exact issue. Have bailed back to v17 and will monitor this thread to see when it's safe to update back to 18.
