I've been using Ignition regularly for a couple of years now and in the past 6 months or so I've noticed an issue that I've never seen occur before. Every once and a while when working on a project in designer, I will try to save and instead receive a popup that says "Unable to save session props". I'm not sure what exactly triggers it, and it varies in frequency from gateway to gateway. It could happen never or within 2 minutes of opening designer. When it does happen, it seems like the only option is to restart the designer immediately to minimize the amount of work lost. Anyone have an idea of what causes this or how to stop it?

Have the same popup after I update to 8.1.47, never seen before.
If you're on macOS, this post may be related.
@zac.orange, what OS are you running? and what version of Ignition?
EDIT: actually I guess the dialog styling says it is Windows.. Ignition version might still be relevant though.
I have the problem on Windows
This happens to me as well, I'm on 8.1.47 in Windoze. I don't think I've had the issues before in other versions
I've never seen this in Linux.
I find zero results when I search our issue tracker for "unable to save session props"... you've gotta open support tickets for these things.

Was there any solution to this on Windows? I'm running into the exact same issue; Windows 11 v24H2 Build 26100.3775
Ran into this today, as well. Running Windows 23H2 Build 22631.5039
