i have the similiar problem when launching from renderdoc i launch directly in vulkan mode, then it triger the assertion below

here returns VK_ERROR_DEVICE_LOST

then i switch to version 1.50, the problem does not exists, it's too hard to find what is changed in vulkan.cpp compared to version 1.50 due to the merged commit. i will be very glad if the author could provide the whole commit history, it will be easy to find the problem by checkout to the history commit
