Bence J. yeah this could happen for a whole host of reasons and I have not been able to successfully troubleshoot or pinpoint a solution for when this error occurs. Like, if you sent me that exact SVG, I'm sure I'd be able to paste it in just fine....
The only thing I can think of to do would be to consider reinstalling the chrome extension but I really dont know if that would work or not. Make sure your chrome and the extension are both fully updated.
