[HELP] Game Crashing when joining Co-op

[Tigr0705]

So my friend and I had a bunch of mods downloaded, and today it just randomly decided that my friend could not join my co-op world. SMAPI gave the following error messages (see below). They tried to redownload the game and not even run it through SMAPI but it crashes every time she tries to join the world. I can join her world fine but she cannot join my world. Does anyone know how to help fix this? The game starts up fine, it just crashes after inputting the invite code and clicking on the world.

So update:

I believe the problem is that I have these two Boots in a drawer in the game that came with one of the mods, but I deleted the mod and the item is still in there as a glitch, which is causing the game to glitch. Is there any way for me to manually delete these glitched items from the code or the save files? I've attached a picture of the two shoes that have no picture.

You can delete them from your save, yes. The save files are just XML files with all the spaces squeezed out. (As it says in the section of that page on how to edit them, make a backup first!) Look for XML elements with the start tag <heldItems xsi:type="Boots"> through the end tag </heldItems>. Two of them will have <DisplayName> elements inside with the names of the pairs of boots you're looking for. Delete both <heldItems> blocks in their entireties. For example, here is a block that would be deleted as a unit to remove the Combat Boots from a Dresser or Chest:

<heldItems xsi:type="Boots">
    <isLostItem>false</isLostItem>
    <category>-97</category>
    <hasBeenInInventory>false</hasBeenInInventory>
    <name>Combat Boots</name>
    <specialItem>false</specialItem>
    <SpecialVariable>0</SpecialVariable>
    <DisplayName>Combat Boots</DisplayName>
    <Name>Combat Boots</Name>
    <Stack>1</Stack>
    <defenseBonus>3</defenseBonus>
    <immunityBonus>0</immunityBonus>
    <indexInTileSheet>508</indexInTileSheet>
    <price>150</price>
    <indexInColorSheet>4</indexInColorSheet>
    <appliedBootSheetIndex>-1</appliedBootSheetIndex>
</heldItems>
