My opinion about this:

As far as I know the warning of the US to its citizen to leave Russia is related to the arrest of a US journalist for spying in Russia.

US journalist Evan Gershkovich has been arrested in Russia and accused of spying while working for the Wall Street Journal.
An experienced Russia reporter, he was working in the city of Yekaterinburg at the time of his detention.
The White House has condemned his detention "in the strongest terms".
The Kremlin claimed he had been caught "red-handed" but the Wall Street Journal vehemently denied the allegations against him.
