Coherence fail after suspend/resume

[pDavid]

I have MacOS 26.2 and Parallels Desktop Version 26.2.0 (57363). I have a Windows 11 virtual machine, specifically Windows 11 Pro 25H2 with all Windows Updates applied.
My issue is that after I suspend this virtual machine and resume, Parallels posts a message "Unable to switch to Coherence". My work-around is to reboot the virtual machine, but I would rather not. I suspend my virtual machines a lot.
Any suggestions?

Hi Keshav, is there any update on this? We have the same problem and even with the last update this problem still persists.
