Can a Bad Language Grade Affect My Chances of Admission?

Hello! I wanted to know how much a singular language class could affect my college application.

I have taken language classes all of high school so far, two years of Japanese, with a middle school Japanese class that counts for high school credit. This year I decided to take Spanish as an IB class. I am going to be moving for the third time of my high school career, so next year I won't be able to finish my Spanish class since I will be going to an AP school. This means I will not receive predicted grades for the college to look at, but rather a finalized grade from the assignments this year.

I wasn't exactly great at Spanish, although I got decent grades on my assignments. I do an online Spanish course, so sometimes my schedule wouldn't line up with the teacher's and my grade would be brought down for missing an oral. What I'm really scared about is how my final exam is going to affect my score- I believe it might bring my 5~6 to a 3, which is barely passing to me. I've gotten great grades in all my other classes as well as my previous language, so will the admissions office take that into account? I don't want one singular bad language grade ruin my whole application. I'm also not planning on getting a degree closely associated with language or going to a prestigious university.
