Big delay after click on plasma-shell?

Lately I’ve been having this issue where there is a big delay between clicking on a plasmoid on the shell and it showing the miniapplication. This only happens after first boot or after restarting the shell.

This is my system info:

Operating System: NixOS 26.05
KDE Plasma Version: 6.6.6
KDE Frameworks Version: 6.26.0
Qt Version: 6.11.1
Kernel Version: 7.1.10-zen1 (64-bit)
Graphics Platform: Wayland
Processors: 12 × AMD Ryzen 5 4500 6-Core Processor
Memory: 32 GiB of RAM (31.1 GiB usable)
Graphics Processor: AMD Radeon RX 6600

Looking at your YouTube video, that is an issue with the hard drive? Maybe, i dunno.

Some extra info:

Checking journald, whenever I click the volume applet after a restart I see

Invalid path data; path truncated.
