Travel to Russia under current conditions: Do I need a visa if I reside in country X as citizen of Y (but would not require one as citizen of Z)?

Russia has recently lifted travel bans for nationals and residents of some countries (see, e.g., here). I happen to reside in one of these countries (Germany) and as an EU citizen (Italy) automatically have a residence permit. In addition, I have dual citizenship and also hold a passport of a country (Brazil) for which a visa is not required to travel to Russia under normal circumstances, but which is currently still affected by the Russian travel ban.

Can I travel to Russia under the current circumstances? Do I need a visa as an Italian citizen? Or can I enter Russia without a visa with my Brazilian passport (along with adequate evidence of residence in Germany)?
