K-lite 14.0.5 Icaros [disapearing icon's thumbnails in W10]

I recently intalled K-Lite Codec Pack Mega, last version for 2 April 2018.
My thumbnails in W10 x64 started to disapear shortly after appearing.
It turned out that culprit was "Icaros" added with K-Lite.
Simply deleting dll didn't help. I had also to disable manually entries in shexview, and the immediately everything started to work.

Since the last update of K-lite 14.1.0, Icaros was updated to version 3.1.0 b1, but I don't know if update covered this bug, but I came out with conclussion that it will be better to write here anyway, and maybe in future I'll write if new version actually fixes the bug.

This is not a known bug. Do all thumbnails disappear, or just some? Do new files give a thumbnail (temporarily)?

Clear thumbnail cache + reboot might fix it.

After updating to K-Lite 14.1.0 problem has been fixed.
