Fusion Not Responding after Big Sur Upgrade

[JJas007]

I am running VMware Fusion 12.2.4 on a Late 2013 MacBook Pro.  I recently upgraded to Big Sur 11.7 and Fusion will not start.  I get “Not Responding” in Activity Monitor and have to quit the application.  Fusion ran fine previous to the upgrade.  I do keep up to date with MAC OS and Fusion upgrades and apply them as they become available and I am notified.

It seems I had this problem in the past but cannot find the solution!  I don’t remember the time nor the various versions.

Any suggestions or help is greatly appreciated!

Thanks,

John

I am having the same issue but my Fusion bundle is located on an external hard drive. All worked fine until Big Sur. Updated Fusion to v12 but still not working....

Try a complete manual install of Fusion 12 per KB article https://kb.vmware.com/s/article/1017838 This not only uninstalls the Fusion application but other support files outside of the application.

Then reinstall Fusion 12.

Thank you. Will try this...

Still no luck. Getting same error message....

My apologies for not replying sooner!  I found, through much searching, that the issue eventually goes away if you just let Fusion sit there trying to restart a VM.  My readings said it can take from several minutes to up to 6 hours.  Mine eventually came back in about 3 hours.  Has been working fine since.

Seems no one knows why this happens and a post from a VMware employee says they can't reproduce the problem to do any kind of investigation!

Thanks to all that read this thread and offered any kind of suggestion.
