Unable to install a specific mod :/

[TalviVex]

Ive been able to install other mods just fine, both through the nexus website modmanager download and through stardrop itself. Neither is working for this particular mod :( I'm not super good at deciphering the error and what to do so I would love it if someone could help :)

This is the mod if it matters: https://www.nexusmods.com/stardewvalley/mods/31485
