I have, it still breaks - though the readout is different

Converting to 5.0 gives an impossibly large memory error, and 5.2 gives a serialization error. I’m not sure if these issues are separate or stem form the same source. Either way I’m not sure how to approach them aside from deleting all substance files and reimporting them. I would like to avoid that if possible however, as this is a huge project. I’ve also tried the usual solutions of deleting the build folder and saved folder.
