I can't download the curse forge mod, it's blocked by my antivirus.

Can't confirm this issue. Probably you have some weird configurations for your protection tools (like a fully blocked executable files or something similar).

but I can download the previous version of the mod

This still means nothing. I've downloaded the latest version from CF and ran it through virustotal to be sure.

Well, idk. It still looks like an issue of your protection tools. I've just decompiled .jar file, and it looks fine - code is valid, there is nothing third-party inside.

ok, thanks for the help
