I didn't stop my recording properly, can I still recover my Video?

Last friday I did a screen recording and at the end, instead of clicking on "stop recording" I just closed my laptop, then 10 minutes later opened it again, realised I didn't stop the recording and pressed the stop recording button. The video was supposed to be 30 minutes long, however it only saved about twelve minutes. I did record it as a .mkv file. Also OBS is still open in the background and is using like 30 - 50% of my CPU. Can I somehow restore the rest of my video?

PS: The Log file I have attached is not the original as it would have been too big for the site apparently (it has about 15.000 kb). I copied out the most important part because in the end it just repeated the same error message that ist also included in this log just not a thousand times repeatedly.

If you recorded as mkv, you should be able to use the video up to the point where you closed your laptop. If media players refuse to play it, use File > Remux recordings to write the video with refreshed file structure to a new file.

Thank you for your reply,

I can play the first 12 minutes of my video, my question was werther I could recover the 18 missing minutes, becuase I recorded for 30 minutes in total
