Input is clipped/overdriven. This happens if the output signal of the mic is so high it cannot be measured by the analog/digital conversion process. You need to lower your microphone level and/or avoid screaming.
It can also be the result if you set a too high volume gain. Make sure you never used any gain above 0 dB. This is the first thing you should make sure before everything else.
If you must include screaming, you can use a compressor filter to even the volume and reduce clipping.
It works like that:
First, you need to adjust your mic level so screaming will not overdrive. Scream into your mic the same way you did in the video and adjust the level so it doesn't "buzzle" in the recording. You will probably need to adjust the mic level in the Windows settings, not necessarily in the OBS settings, because the clipping will probably appear in the Windows microphone device driver.
You will find that if you speak normally, your normal voice will be too low at this point. Add the "Compressor" filter to your mic source. Adjust the "Output gain" value so your normal voice is back up again. The screaming parts are lessened now and not clipped.
If you are not satisfied, read the compressor filter description and adjust the other values as required:

If you are still not satisfied and cannot avoid "buzzling" while at the same time keep the lower volumes audible, add the "Limiter" Filter after the Compressor filter and adjust its threshold, so the buzzling finally vanishes. Limiter only without compressor will probably work also, but the output will probably not be as well, because the Compressor first evens out the dynamics better.
