Parallels in Catalina: Office 365 (in Windows) crashes the Mac

Can I confirm that this has NOT been resolved in the latest update? I am scared to start up Parallels as I don't want to crash my Mac. I rely on latest directx implementation on parallels 15, so can only use it when I don't run my eGPU. This has been going on for almost 6 months :(
 
Now that I'm working from home every day due to the COVID-19 measures in the UK, I've also been experiencing the crash since I had also started using the Blackmagic eGPU with my Mac Mini (2018) a week ago. My Mac crashes once or twice a day (about two minutes after the screens freeze), and the logs report an issue with WindowsServer each time. I'm running the latest version of macOS Catalina 10.15.4 and Parallels Desktop 15 Pro Edition Version 15.1.3 (47255).
 
Same issue here:
eGPU, MacOS 10.15.4, PD15.
Crash after a few minutes. I've sent the technical details.
Please help.

Sadly, the problem continues with the latest version of Parallels Desktop Pro Edition Version 15.1.4 (47270).
 
This has been an issue for almost 6 months now, I've given up using parallels when connected to my egpu and none of the technical support here are able to provide anything of use. Won't be renewing my subscription if this continues.
 
I am having the same issues on my 2017 15" MBP when using eGPU (Radeon RX 480). Using any of the Office 365 apps (Word, Excel, Skype) completely crashes Catalina. Even after reboot it takes awhile for the system to stabilize due to all the disk checks. Non Office 365 apps do not appear to cause any issues. Agree with others that this needs to be addressed before I renew my subscription.
 
+1 (everything OK when using internal graphics, crashes with Outlook 365 running when eGFX is connected)
Please fix this.
(Mac OS Catalina 10.15.4, Parallels Desktop 15.1.4, eGFX (Sapphire Radeon RX 580, Sonnet 550)

Three days ago I upgraded my computer from 2012 iMac to 2020 iMac with 2nd monitor (an LG 5K 27") . I am now finding that Excel regularly freezes. The activity monitor app shows the windows cpu process running at over 100% of cpu when excel is frozen indicating to me some kind of loop that doesn't end, but what would I know. I do want a fix, as I use excel for 10 hours a day. Is it recommended to go back to Parallels 14? I am on 15.1.4 (47270). If so how do I get v14?
 
Is there any response or update from Parallels, this is a reported issue for several users, are your devs looking into this? we've been talking about this for months now
 
I am also having this issue. 2018 Mac Mini with Razer Core X and RX 580. Running Visio in Windows 10 (with all OS and software updated) randomly freezes and then restarts the computer. Very frustrating. Parallels 15 is unusable in this state.
 
I'm also having this issue. 2020 Mac mini with external GPU (Razer Core X and RX 580). I've found that disabling hardware acceleration in Office stops the crashing. It's best to do it via the Registry Editor since it's difficult/nearly impossible to disable within Office itself due to the crashing. The link below (Method 2) provides instructions:

Hopefully the Parallels team can provide a more permanent solution to this bug so hardware acceleration can be re-enabled in Office.
 
Thank you stoli412. I was able to get Word open long enough to turn off hardware acceleration in Office. I haven't done extensive testing, but this seems to have solved the issue. I appreciate the tip.
 
I also have the same issue, renders parallels completely unusable, what's worse, it takes the entire Mac with it rather than just Parallels itself.
I am on a MacBook Pro 16" with 10.15.4 installed. Parallels 15.1.4 (47270) and Windows 10 1909 Build. Gigabyte eGPU with an RX580.
Clean install worked great, the instant I installed Office apps for remote training, crashes started.
I'm surprised to see that this thread has been around for many months now and it still hasn't been fixed by Parallels.
 
Hello, guys, the issue is under investigation with the Parallels Engineering Team.
Also could you please add this Boot flag : video.metal=0 (VM Configuration -> Hardware-> Boot order -> Advance settings) and check the issue.
Please share any results with us.
 
Setting the video.metal=0 boot flag so far seems to have stopped the crashing.
Been clicking around in Outlook and Teams. (which previously would crash within about 20 seconds of opening, give or take 10 seconds. Also the crash was never immediate after opening them, but even when not interacting with it after a few moments would crash, if that helps your team track it down in any way)
