That sounds like a problem, until you look at the historical rate-of-turnout data. The turnout percentage for black voters in presidential elections usually runs around 60%, about what this poll suggests. It got closer to 70% for the two elections involving Barack Obama, but there was a clear reason for the enthusiasm in those cases. It also spiked up a bit in 2020, but so did turnout in all demos that year, thanks in part to cabin fever. In the midterms of 2022, turnout among black voters only got to 40%. 

This looks more like business as usual, although that's not to say Biden doesn't have a problem. The real danger is that black voters motivated to come to the polls may be doing so to boot Biden out of office.
