FAQ
Reader questions
Why does Slay the Spire freeze on the loading screen on my PC?
Corrupted save files or incompatible mods often cause the loading screen to hang. Rename your saves folder and launch without mods to isolate the issue.
Can antivirus software block Slay the Spire from starting?
Yes, overzealous antivirus or firewall rules may block the game files. Add an exception for the game directory and launcher to prevent false blocks.
Why does the game close immediately without any error message?
This usually points to a crash in the early startup code, often linked to graphics driver issues or corrupted user profile data. Update drivers and try a profile reset.
Is Slay the Spire compatible with older laptops or integrated graphics?
The game runs on modest hardware, but drivers and missing runtimes on older integrated graphics can stop it from launching. Install vendor updates and required runtimes first.
