KDE Plasma initialization delay. I found the delay with journalctl -b, but I couldn't interpreted the log that is causing the delay

I have been facing for a while now a considerably big delay on my Plasma startup with no SSD activity. I found at my journalctl -b output a delay point.

This appears a lot around the delay: snapd[938]: udevmon.go:190: udev monitor observed remove event for unknown device, but I have no clue what it means and google it didn't help.

I marked the delay point with --delay--. Just roll down and you'll see it.

I have been facing for a while now a considerably big delay on my Plasma startup with no SSD activity. I found at my journalctl -b output a delay point.

This appears a lot around the delay: snapd[938]: udevmon.go:190: udev monitor observed remove event for unknown device, but I have no clue what it means and google it didn't help.

I marked the delay point with --delay--. Just roll down and you'll see it.

I have been facing for a while now a considerably big delay on my Plasma startup with no SSD activity. I found at my journalctl -b output a delay point.

This appears a lot around the delay: snapd[938]: udevmon.go:190: udev monitor observed remove event for unknown device, but I have no clue what it means and google it didn't help.

I marked the delay point with --delay--. Just roll down and you'll see it.

I have been facing for a while now a considerably big delay on my Plasma startup with no SSD activity. I found at my journalctl -b output a delay point.

This appears a lot around the delay: snapd[938]: udevmon.go:190: udev monitor observed remove event for unknown device, but I have no clue what it means and google it didn't help.

I marked the delay point with --delay--. Just roll down and you'll see it.
