Hi @ilovepi, I did a bit of digging and it seems that this problem comes down to RecordsByBlock[] not being initialized properly (the RIDs are all 0). This may be due to MS VS2019 having trouble with the combination of std::initializer_list and constexpr.

Perhaps it would be good to not combine these 2 constructs for now or only use them conditionally when MSVC is not used.
