Don't you mean /DefaultCompany/HolderOfPlace XD.
Here is the log from a clean run where I start the game and enter the tutorial. (I admit I did then quit through esc accidentally instead through normal quit, but that shouldn't be a problem).
To me it looks like an issue with regional settings, specifically number formatting. Perhaps it doesn't like the Polish use of "," as decimal separator or something like that (Though changing that separator to "." doesn't seem to fix it). I assume the browser version doesn't have this issue due to one more degree of separation from the system where the browser mitigates it in some way.
