Surely related to: [[Bug] Embedded browser fails to correctly start on b2019030502](http://forum.inductiveautomation.com/t/bug-embedded-browser-fails-to-correctly-start-on-b2019030502/23065), would’ve commented there but thread is locked.

my last Ignition install was 8.0.5 on Server 2016, working well then, but haven’t touched it until new install yesterday of 8.0.10 on Server 2019.

Replaced Designer Launcher (macOS) with new from 8.0.10 gateway, now can’t open **any** Perspective views on **either** Ignition instance.

Renamed `.ignition` to `.ignition.old` for good measure, no effect.

I don’t think you’ll be able to run the designer or browser component on Server 2019 until we finish the JXBrowser upgrade. Their release notes say version 7.4 officially supports Server 2019 and that’s the version we’re working on integrating.

Clarification, Designer Launcher is running on macOS Catalina 10.15.4, connected to Server 2019/2016 gateways - does the same limitation you described above apply to this version of macOS?

No, should work fine on 10.15.4. Probably half our developers are using macOS without issues.

@PerryAJ do you know what this is about?

Can’t duplicate this issue after installing macOS Catalina 10.15.4 Supplemental Update

Might have just been the reboot that helped. Let us know if you see it again.

Happened again, reboot (of my mac) resolved. Strange. Also had some issues renaming “template” views referenced by other views - got spinning ball of death, force-quit designer b/c I was impatient. Those issues also seem to be resolved after reboot. Can’t reproduce now, though I’ve recreated/saved those views in question - crash happened while they were newly created/unsaved to gateway.

When I first re-launched designer/connected to gateway after reboot, instead of auth dialog straightaway, got a “downloading…” dialog (as if it was first time connecting to gateway), but only seemed to download a couple files, then presented auth dialog. I had previously restored a project backup, but had also already tried to open it (concurrently with an existing designer session - that’s when i got the "unable to deserialize) error again, so can’t imagine it was re-downloading the project.

Will report back if I experience it again, and will hopefully be able to reproduce.

Currently using launcher 1.0.10 to access both 8.0.5 and 8.0.10 gateways

Happens concurrently with another designer instance experiencing the failure to open existing views (same gateway, different project).

reboot resolves. I’m baffled.

Think I’ve found the culprit - seems that Better Touch Tool’s “Doubleclick Main Menubar” trigger conflicts with Ignition Designer somehow.
