is there a nice and simple way to see how worldsheet weyl anomaly
translates into target spacetime lorentz anomaly, in bosonic string
theory?

D=26 Anomalies in Bosonic String Theory refers to a specific issue that arises in the mathematical framework of bosonic string theory. In this theory, the equations that describe the behavior of strings in 26 dimensions become inconsistent, or "anomalous", leading to problems in the formulation of the theory.
D=26 is significant in bosonic string theory because it is the critical dimension at which the theory becomes inconsistent. In other words, if the number of dimensions in the theory is less than 26, the equations are under-constrained and the theory cannot fully describe the behavior of strings. On the other hand, if the number of dimensions is greater than 26, the equations become over-constrained and lead to contradictions.
D=26 anomalies have a significant impact on the validity of bosonic string theory. The inconsistencies that arise in this dimension make it impossible for the theory to accurately describe the behavior of strings. As a result, the theory cannot be considered a complete and valid description of the fundamental forces of nature.
There are several proposed solutions to D=26 anomalies in bosonic string theory. One approach is to modify the theory by adding new dimensions or incorporating other fields, such as fermions, to cancel out the anomalies. Another approach is to consider bosonic string theory as a low-energy approximation of a more fundamental theory, such as superstring theory.
The implications of D=26 anomalies for our understanding of the universe are significant. If bosonic string theory is not a complete and valid theory, it means that our current understanding of the fundamental forces of nature is incomplete. It also suggests that there may be other dimensions and fields beyond what we currently know, and that a more comprehensive theory, such as superstring theory, may be needed to fully describe the universe.
