I am also able to reproduce this, again with specific tracks triggering it 100% of the time. Plasmashell will also freeze immediately when restarting after being killed, if one of the offending tracks is already playing at the time.
I got a backtrace from gdb which seems to show plasmashell is stuck trying to paint an SVG? I tried a few times and all backtraces are largely the same up to KSvg::SvgPrivate::findInCache.

Created attachment 172897 [details] Video of plasmashell freezing when playing specific tracks SUMMARY Plasmashell freezes when switching to specific tracks in Elisa with the Media Player widget in a panel STEPS TO REPRODUCE 1. Have the Media Player widget added to a panel 2. Have a playlist in Elisa with specific tracks 3. Skip tracks until it freezes plasmashell OBSERVED RESULT Plasmashell freezes and does not recover EXPECTED RESULT Plasmashell does not freeze and remains responsive SOFTWARE/OS VERSIONS Operating System: Fedora Linux 40 KDE Plasma Version: 6.1.4 KDE Frameworks Version: 6.5.0 Qt Version: 6.7.2 Kernel Version: 6.10.6-200.fc40.x86_64 (64-bit) Graphics Platform: Wayland Processors: 16 × Intel® Core™ i9-9900K CPU @ 3.60GHz Memory: 31.1 GiB of RAM Graphics Processor: NVIDIA GeForce GTX 1080 Ti/PCIe/SSE2 ADDITIONAL INFORMATION Elisa version: 24.05.2 When it skips to a track which causes a freeze, I see the following line in my journal Aug 23 23:20:57 kathdesktop elisa[4363]: [mp3float @ 0x5588c79f7780] Could not update timestamps for skipped samples. Using pkill -9 plasmashell will restore plasmashell. Although if one of the troublesome tracks is still playing, plasmashell will not begin. I have been able to reproduce this with the same tracks that seem to trigger it. I have attached a video of how it crashes. Showing expected functionality, until it reaches a track which causes a freeze. In this example, Thirty Seconds to Mars - Walk on Water
