HookWebpackError: Expected a pseudo-class or pseudo-element.

[spare heart]

Hi guys,
Im migrating from v6 to v7 on mantine and now everything looks and works peroperly but when trying to build i keep getting "HookWebpackError: Expected a pseudo-class or pseudo-element. " error.

I have been troubleshooting for over 3 hours without any progress, I do know there must be any css syntax error but I cant find anything, been running stylelint, checking every line, debugging and debugging.... when commenting out all the css the problem dissapears.

Has anyone had a similiar problem or got any tips, much appreciated.
