Failing to compile on 1.12 nightly

I have been finding that some of my unit tests have been consistently failing on the 1.12 nightlys for several months, I think due to BlockArrays.jl. I am not sure if this is a known issue? I am having trouble parsing the error to understand if there is something I should be modifying on my side in the package that depends on BlockArrays via BasisFunctions. The unit test run is here, with the relevant error posted below.

ERROR: LoadError: The following 1 direct dependency failed to precompile:

Start by reproducing the reported precompilation failure with Julia 1.12 nightly using the linked apMADGICS.jl workflow. Inspect src/abstractblockarray.jl around lines 186-187 and the surrounding BlockArrays loading path; done means BlockArrays and the dependent BasisFunctions package precompile successfully on that nightly.
