I would suggest you start looking into this thread as it is most likely you have the same issue. https://www.loverslab.com/topic/93393-bdo-armor-pack-for-sse-crash-when-hovering-over-armor/ In my opinion, it's most likely a texture/ cubemap issue. Also, check with xEdit that the mod is in the correct form (file header should be form 44, if not you can fix it easily in Creation Kit) and perhaps use Cathedral Asset Optimizer and run your mod through it (https://www.nexusmods.com/skyrimspecialedition/mods/23316). It might fix most mesh/ texture issues. NOTE: If you run the mod through Cathedral Asset Optimizer, MAKE SURE that you use it on a backup copy of your mod. It doesn't create a new copy, it overwrites the mod you selected. If the issue persists after this, you will probably have to look into texture/ meshes individually. Pretty tedious job.
