Texture array should exist

Error message

Texture array should exist

What it means

Internal invariant panic in bindless resource cleanup: the texture array slot for the given bindless index was missing when removing a binding. Indicates bindless state bookkeeping corruption (double free or missing allocation); not expected in normal operation.
