Hi, please provide additional crash info:

[claudiux]

Fixed by linuxmint/cinnamon-spices-themes#846

[vlad0337187]

@claudiux , sorry, I named that PR wrongly, it doesn't fix this problem,
I just removed lines causing crash in that PR.

But problem still exists, you can't use "text-shadow" property in specified class and id anymore (on Mint 22 it was possible).
