Windows, it originally started crashing after starting a game an quitting out of it cause I accidentally skipped some dialogue. I tried uninstalling which didn't help and restarting my pc.
Hmm... that's an interesting issue, I (Rriik) have never run across it, but if it persists even after deleting and redownloading all the files it likely means it's related to the persistent data (saves, config files and the persistent dialogue history used for skipping). If you can open the game and look at the options menu, there should be a button to "Browse user data" which will open up the persistent directory. Try deleting the persistent.json file and restart the game, and let me know if it fixes the issue. (The folder location should be under "C:\Users\<user>\AppData\Roaming\Godot\app_userdata\Identity Visual Novel" in case you can't open it through the game).
