still having this issue as well
hopefully a fix soon

Same here

Here's how I solved it:

Unsubscribe from all mods.
Uninstall Slay the Spire.
Go to your folder: Steam > steam > cached.
Select everything in the cache folder and delete.
Reinstall StS
Subscribe to only Mod the Spire.
Play with Mods
Mod the Spire window should now show up.
Re-subscribe to BaseMod, StSLib and any other mods.
Fixed!

This is how I did it. Maybe just clearing the cache will work, but these are the steps I took to make it work.

Good Luck!

thanks

where????? there is no cache folder!

For me once I changed the mod order it worked.

goto Library -> Right click on the game (from the list on left) -> Properties -> Workshop

Then you see the list of mods that you are subscribed to, and you can drag and drop to change the order.

Move the "ModTheSpire" to the top of the list and it worked for me.

No matter what I do, it ain't working... like AT all. Already tried the stuff from the previous comments but nope, still gives me the same message that it is apparently not installed, is there maybe like a different way to manually put it into a folder? A version that actually works too or whatever?

this probably isnt the same issue most of you are having but for me i subscribed to mod the spire while having a different game updating so i had to select STS to download now

After trying this, what did it for me was enabling the game to ask if I wanted to start with mods. Just go to Properties > General > Launch Options, and set it to Ask when starting. Also, make sure you start the game from your Library—not from a desktop shortcut.
