There's quite a lot of data that points to a decline in many places... literacy scores are lower, math scores are lower, etc.
The effects appear to be quite bad, and haven't yet recovered in many places (especially among lower income groups). This will take some more time to distill with more accuracy, but lockdowns and remote schooling almost certainly had a negative impact.
