Chelsea owner Roman Abramovich has already been sanctioned by the UK government, which is having a first-hand effect on the club and its everyday operations. As of right now, they're not allowed to buy or sell any players, with the summer window only a couple of months away. Also, Chelsea's bank accounts have been frozen by Barclays after there was a limit put on their spending for home and away games.
Now, the Premier League has completely cut ties with Abramovich, disqualifying him as the director of the Blues. Via Fabrizio Romano:

Here is the league's statement on the matter, per ESPN:
“Following the imposition of sanctions by the UK Government, the Premier League Board has disqualified Roman Abramovich as a Director of Chelsea Football Club. The Board's decision does not impact on the club's ability to train and play its fixtures, as set out under the terms of a licence issued by the Government which expires on 31 May 2022.”
As noted, Chelsea is under this government license until May 31st. However, this is certainly disrupting the club, especially when it comes to fans. Only season ticket-holders can attend matches at Stamford Bridge, which means the stands are certainly going to be relatively empty at times. No tickets can be sold and all the club stores have also been shut down, therefore the Blues can't make any money from merchandise.
As for Abramovich's potential sale of Chelsea, it's still expected to be done. The Russian can apply for a separate license to continue the process, but he's undoubtedly going to have to take less than the $3.9 billion asking price given all the turmoil at Stamford Bridge.
