The Guardian has a few more examples:
One conspiracy theory aired on Kremlin-backed Sputnik radio in February drew a parallel between the 19th-century opium wars and coronavirus, implying that “England” and unnamed “international organisations” were seeking to control Chinese internal affairs, just as the British empire forced China to open its markets and cede territory at gunpoint.
Meanwhile, the website Ria Fan claimed that a “false panic” about Covid-19 would benefit pharmaceutical companies looking to make “lucre” from the virus. And against a soundtrack of menacing music, Ren TV’s Military Secret documentary claimed the virus could be a “biological weapon” disseminated by US special forces in China.
And also a bit more commentary from the leaked EU report:
Researchers at Cardiff University’s centre for crime and security research, who carried out research with the commission, found an evolution in tactics by pro-Kremlin media.
Rather than authoring disinformation, Russian sources were amplifying theories that had originated elsewhere, such as China, Iran or the US far right, the researchers said. “This tactic allows them to avoid the accusation of creating disinformation themselves, claiming instead that they are merely reporting what others are saying,” the report stated.
But I'll also note here from the same source that (officially) Russia has strongly denied doing any of this
Russia has strongly denied the accusations. “If there was even a single concrete example, I could comment on it, but once again they are just unfounded accusations,” said a spokesman for the Russian president, Vladimir Putin.
I suppose one gets into a debate here how much state control Russia exercises over channels like Ren TV etc. (From the Wikipedia page on the latter, I see there has been concern within Russia itself, e.g. from their Science and Education ministry, that Ren TV has aired pseudoscience on other occasions.)
The EU (probably the US too) generally see[s] little difference between the privately owned Russian channels and state propaganda, as discussed on a EU-sponsored site:
A journalistic research project undertaken last year by the independent Russian news outlet RBC showed that RIA FAN, the mother company of “USA Really. Wake Up Americans”, is in fact itself an offspring project of the famous St. Petersburg “troll factory”. RIA FAN shared its first address with the trolls before moving into its separate premises; however, according to RBC, the owner remained the same, namely Yevgeny Prigozhin, who is currently criminally charged in the United States for his participation in a conspiracy to “sow discord in the U.S. political system,” including the 2016 presidential election. [...]
Indeed, with the prospect of running both a national news agency (RIA FAN) and international version (USA Really. Wake Up Americans), Yevgeny Prigozhin’s private media holding begins to resemble first of all the Russian government’s Rossiya Segodnya media holding, which also controls both a national news agency, RIA Novosti, and one of the official international propaganda online resources, Sputnik, tied together under the leadership of the EU-sanctioned propagandist CEO Dmitry Kiselev.
Gradually, it becomes difficult, and thereby also less and less relevant, to distinguish between the pro-Kremlin propaganda that comes from outlets owned and controlled by the Russian authorities, such as RIA Novosti and Sputnik, and the privately owned and theoretically independent, but no less Kremlin-loyal outlets, which, as RIA FAN and its new international offspring, depend on schemes involving both the government’s political approval and the government’s money.
[If you're confused about that: "USA Really. Wake Up Americans" is the official/real name of a Russian privately-owned "information agency"...]
