Created attachment 159219 [details] Can't open anything through main K menu, Task Manager, or Desktop Operating System: Kubuntu 23.04 KDE Plasma Version: 5.27.4 KDE Frameworks Version: 5.104.0 Qt Version: 5.15.8 Kernel Version: 6.2.0-20-generic (64-bit) Graphics Platform: Wayland Processors: 12 × AMD Ryzen 5 PRO 5650U with Radeon Graphics Memory: 14.4 GiB of RAM Graphics Processor: AMD Radeon Graphics Manufacturer: LENOVO Product Name: 20XF004SUS System Version: ThinkPad T14s Gen 2 ADDITIONAL INFORMATION I can't open *anything* in the K menu or from the task manager. I'm getting a "Resource error (fork failure): Cannot allocate memory" error for everything, see attachment. Also, none of my desktop icons are viewable. I have 16 gigs of memory total, and have been running Kubuntu for a year without any real problems. I don't know what update brought on this behavior? Running free -h shows I have 9.1Gi left, so I don't know what is going on. The only way I was able to even open Firefox to file this bug report was krunner. So far, I've been able to open most things through it, or typing into konsole once I opened that through krunner, but this is a huge inconvenience.
*** This bug has been marked as a duplicate of bug 469445 ***
I don't appear to have a memory leak, so I don't think the suggested bug that this was listed as a clone is accurate. I'm reopening this ticket.
William, my memory usage also looks normal when bug 469445 occurs. Did you try deleting the [ScreenMapping] section in .config/plasma-org.kde.plasma.desktop-appletsrc as described in that bug?
