For some reason, when I opened the game it will just get stuck to the screen that says loading for a few seconds while the cursor is a blue circle and then the game just, close.

This generally happens when someone tries to run the game without extracting all of the files from the Zip archive, or when buggy or conflicting mods are applied.

The Debug mod can be used to diagnose the cause of the error, though it also changes the crashing behavior of the game, but it does not fix errors. https://itch.io/t/1137280/debugmod-v10d

If mods were applied, then the best solution is to delete the Strive program folder and extract a new copy.
