Are these workstations isolated from the internet? If so, you may need to disable certificate revocation checking. ---

Just to add to the mix here, I am not seeing any slowdown when running Designer from a Linux client. My Windows client however does take several minutes to start Designer, so I am guessing something specific to Windows. Anyone with a Mac having issues? ---

We are also having issues with designers getting stuck loading "Starting module: perspective" for several minutes. Vision clients also get stuck "Starting..." for several minutes after login. These problems have been intermittent for us; Sometimes opening immediately, sometimes taking 3-10 minutes. This is effecting connections to our central gateway and all of our edge machines. (Both local and remote connections are effected) Perspective sessions do not seem effected. (running on Windows systems) ---

I am observing Windows Defender (Antimalware Service Executable) CPU activity greater than 90% during Designer project launches. Potentially a Windows Defender policy update causing this behavior? ---

I was just testing this on a VM. I think I was able to replicate this by triggering a targeted Windows Defender scan on the jxbrowser directory in the .ignition cache when Perspective starts to initialize. Edit: The scan completed but it seems to have still stalled Perspective from loading (finished after 4 minutes). I didn't see any load times greater than 20 seconds until running the scan even with a painfully slow VM ---

Alright, it looks like this was confirmed to be related to the packaged Chromium browser extraction for the Designer due to some change in Windows Defender. > [@Designer/Perspective Workstation slow startup on Windows - advisory and recommended hotfix](https://forum.inductiveautomation.com/t/designer-perspective-workstation-slow-startup-on-windows-advisory-and-recommended-hotfix/101848): > > Recently, a Windows Defender update rolled out that is inadvertently causing dramatically slower launching of the Ignition Designer, Perspective Workstation, and Vision with the Web Browser module installed. This is confirmed to be related to the packaged Chromium browser extraction due to some change in Windows Defender. The remediation options are: Add the directory with Chromium binaries to the whitelist. Rollback the Windows Defender update. Our recommendation is to add the binaries dir… ---

Yes, it was the solution for me and it opened very quickly. Thanks for your help. 🙂 ---
