tModLoader A critical error

[Castled]

I am trying to reload my mod, but when I try to reload it, or publish it, it doesn't work.

Reloading the mod:
The mod(s) have been automatically been disabled.
System.IO.IOException: File not open: C:\Users\Owner\Documents\My Games\Terraria\ModLoader\Mods\CastledsContent.tmod
at Terraria.ModLoader.Core.TmodFile.GetStream(FileEntry entry, Boolean newFileStream)
at Terraria.ModLoader.Mod.<>c__DisplayClass42_1.<LoadResources>g__GetStream|0()
at Terraria.ModLoader.Mod.LoadResource(String path, Int32 length, Func`1 getStream)
at Terraria.ModLoader.Mod.LoadResources()
at Terraria.ModLoader.ModContent.<>c.<Load>b__30_0(Mod mod)
at Terraria.ModLoader.ModContent.LoadModContent(CancellationToken token, Action`1 loadAction)
at Terraria.ModLoader.ModContent.Load(CancellationToken token)
at Terraria.ModLoader.ModLoader.Load(CancellationToken token)

Publishing the mod:
1. Publish using tmodloader
2. File too big! (For now, 5MB)

I need help for this, otherwise the Castleds Content mod will be permanetly broken.
My mod which is still remaining for now unless no one helps : tModLoader - Castleds Content
