Orion RC hung, have some diagnostics

Rougex

I have a Orion window that's hung (no clicks on anything in the website or on the Orion menu above it give any response, except for the Orion window selector, which if I pick another window it doesn't actually bring up). This is 0.99.135.2-rc on MacOS 15.6.1. I have two "Orion RC" apps running, one which I run Kagi Assistant in (which did not hang, and only has 1 tab open), and another for everything else, which at the time of the hanging was a window with 4 tabs and a window with 1 tab. I only have one extension installed, 1Password, and I was not trying to use it at the time it hung, I think I was just reading my gmail.

I ran a sample + spindump script on all of the Orion RC pids on my machine and collected an 850 Gb file (gzipped) file of output like you see below. If you want it, i'll throw it on Google Drive and put the link here. Otherwise, please let me know what diagnostics would be useful for you if/when this happens again.

I expected it to not hang.

Note that when these hung Orion windows are below other windows, clicking on Dock item for Orion RC does not cause any of them to be foregrounded, and when I do manually uncover them, I'm getting the pinwheel of death on the Orion windows.

Wow, thanks for the detailed report! I'll pass it along to the dev team and they or I will let you know if there's use for the full file. How often has this bug happened to you? Have you noticed anything specific that triggers it?

Rougex

Hi Roxy, this has only happened to me once, though I only switched over to using Orion (RC) as my primary browser yesterday! I don't recall what lead up to it, but I'll try to be more mindful if it happens again.

Happened again today, this time going from a Google Sheets tab to a Gmail tab. Spinning wheel of death. Plz LMK if there are any diagnostics you want me to run. (Old Unix wizard - happy to run commands / filter / script / tar gz etc.)
