In Turkish there is a capital İ letter and lowercase ı letter. So when Project Tiny trying to lowercase I to i or uppercase i to I, it changes as i to İ and ı to I in Turkish. This causes build problems because Project Tiny can't see the folder it creates. It doesn't work with Web or Windows builds. I didn't test the rest but I'm sure they will not work too. Here is an error log: https://gist.github.com/YigitVeloxia/4914e1432c53a436c1b1da4b59ba47f9 As you can see it looks for a folder named: "artifacts/lib_unity_tiny_�mage2d_web/spacecolonypa-wasm-spacecolonypa/hom3/dummy.o" but I assume it should be "artifacts/lib_unity_tiny_image2d_web/spacecolonypa-wasm-spacecolonypa/hom3/dummy.o" And even changing the user language to English doesn't solve this problem. Windows should be installed in English or any other supported language to prevent this problem.
