this issue only occurs on some PC devices and cannot be reproduced locally. Can you provide further troubleshooting suggestions?

It looks as if you are running out of stack memory. Do you have any changes to the code in FPersistentUniformBuffers::Initialize? I would suggest checking the total size of all the local variable used in this function using sizeof.

Edit: The maximum stack size is usually 1 MB on Windows PCs.
