So this is going to sound weird but whenever I use thumbnails (from the RA repository) I crash the moment I try to load a game through the playlist when using Vulkan. This only applies to games that have a thumbnail associated with them. So for example, if i delete every NES thumbnail, minus Castlevania, every other game will run fine except castlevania.
Turning off thumbnails through the menu stops it from happening. The only core that does not crash is Mednafen PSX HW.
