This is a bit confusing, you are talking about sharing the "new virtual output" but the stack trace is on the section to stream an output and presumably one that does not exist. How reproducible is this? Is there a chance you can provide the backtrace with debug symbols? For what it's worth, sharing a new virtual output works fine on my system.

i can confirm btw that under wlroots screensharing works
A possibly relevant merge request was started @ https://invent.kde.org/plasma/xdg-desktop-portal-kde/-/merge_requests/184
I've put together the MR above. I think it can and should go in as is, it will help our debugging though if you can try compiling it and testing before 5.27.5 is released so maybe we can have the proper fix in there. I tried setting up new virtual outputs several times, stopping and re-enabling them and it worked well (great actually ^^'). Not sure what else to test.

This crash report is quite old, there have been a lot of changes in the meantime. Can you reopen if the bug still persists with Plasma 6.4 or newer.
