Graduate String Theory in N dimensions?

Click For Summary
String Theory and M Theory are constrained to specific dimensions, with M Theory formulated in 11 dimensions and bosonic string theory in 26 dimensions. The discussion raises the question of whether any version of string theory can operate in any number of dimensions, including infinitely many. Non-critical string theory is mentioned as a potential candidate that allows for such flexibility. This theory does not adhere to the strict dimensional constraints of traditional string theories. The exploration of non-critical string theory opens avenues for understanding string theory in a broader context.

TL;DR
Is there any version of string theory or any related theory (like M Theory) that can be formulated in any number of dimensions (even infinitely many)?
String Theory and related theories like M Theory have strong constraints in the number of dimensions where they can be formulated (for example, in the case of M theory, it is only allowed in 11D or in the case of bosonic string theory is only allowed in 26D.

Since string theory and related theories have existed for several decades (or at least several years) and since there are a lot of physicists working in these kind of theories, I was wondering whether there is a known version of string theory (or any related theory) that could work in any number of dimensions (even infinitely many dimensions)?

Thread 'Questioning the timescape model'

"Supernovae evidence for foundational change to cosmological models" https://arxiv.org/pdf/2412.15143 The paper claims: We compare the standard homogeneous cosmological model, i.e., spatially flat ΛCDM, and the timescape cosmology which invokes backreaction of inhomogeneities. Timescape, while statistically homogeneous and isotropic, departs from average Friedmann-Lemaître-Robertson-Walker evolution, and replaces dark energy by kinetic gravitational energy and its gradients, in explaining...
