Chromium on Debian is reported broken upstream and there is nothing we can do about except forwarding you this information https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1088162 If you are not an expert, use recommended download options, Ubuntu Noble, where we control Chromium and where it works. Be happy that we are able to provide you that (only working) option. Here you can make a donation.
