You have somehow messed up the installation process. The most obvious sign is that it claims that your first error is on line 2594 of sexdescriptions.gd, which should only have 1846 lines. All of the other errors appear to be derived from that first error. It feels a bit like it tried to append the contents of the same file to the end of the file. I'm not certain of the cause, as I'm not aware of any normal processes that lead to this result. I would need to know very precisely what steps were taken to reach that result to understand it, but that is likely far more work that it is worth for either of us.
I suggest deleting the mod folder in appdata and the modded program folder to start over from the beginning. If you need further help running through the process I recommend the Strive Discord (https://itch.io/t/284398/discord) as you will get much faster responses. We've gone through the process many times, so it should only take a few minutes to iron out all of the wrinkles.
