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.
