Obs Studio cannot capture the desktop

My current desktop environment is KDE. After I followed the method on the wiki to force the KDE desktop environment Arch Linux Wiki , OBS Studio was able to record the desktop environment normally. However, every time I boot up, my KDE desktop environment would report the following error.

PID: 1388 (xdg-desktop-por) UID: 1000 (leessmin) GID: 1000 (leessmin) Signal: 6 (ABRT) Timestamp: Sun 2026-03-01 14:14:49 CST (8s ago) Command Line: /usr/lib/xdg-desktop-portal-kde Executable: /usr/lib/xdg-desktop-portal-kde Control Group: /user.slice/user-1000.slice/user@1000.service/session.slice/plasma-xdg-desktop-portal-kde.service Unit: user@1000.service User Unit: plasma-xdg-desktop-portal-kde.service Slice: user-1000.slice Owner UID: 1000 (leessmin) Boot ID: e05012498a7242918a2c109a88f51a7e Machine ID: c6d7f7a5e38142288acdb81aeb35e118 Hostname: r97945hx Storage: /var/lib/systemd/coredump/core.xdg-desktop-por.1000.e05012498a7242918a2c109a88f51a7e.1388.1772345689000000.zst (present) Size on Disk: 1M Message: Process 1388 (xdg-desktop-por) of user 1000 dumped core.

This issue has been ongoing for several months. I can't remember exactly which update caused it. Now that I have some time, I can finally discuss this problem.

Re: Obs Studio cannot capture the desktop

You could delete the contents of $HOME/.config/xdg-desktop-portal/ and also $HOME/.cache/xdg-desktop-portal/.
I should have checked the forum a few days ago, as I had the same problem until then.
You could also test obs with another user first, and it should run without any problems.
