SUMMARY
***
Trying to decrypt a password protected rar file causes Ark to yield a "wrong password" error, even though the password is correct.

Sadly, I can't provide the rar file here since it contains copyrighted material, but if you own the game "Amnesia Rebirth" you can try it yourself. Try to unpack _super_secret.rar in the game files using the key 7UI84S3D3AN2XJ36E7G5J26KA3Y9 and Ark will fail to do so. 

(Maybe I can provide some more information about the rar file, but idk what you could need.)

Also, 7-Zip unpacks this file perfectly fine.

STEPS TO REPRODUCE
1. Try to unpack _super_secret.rar form "Amnesia Rebirth" with key 7UI84S3D3AN2XJ36E7G5J26KA3Y9

OBSERVED RESULT
Unpacking fails with:

Loading the archive ‘/mnt/Games/SteamLibrary/steamapps/common/Amnesia Rebirth/_super_secret.rar’ failed with the following error:
Wrong password.

EXPECTED RESULT
Unpacking should work.
