Some YouTube videos aren't in sync with the audio

I'm having a problem with a couple videos where the video and audio aren't in sync. For example, the video in the first screenshot is only 2:30, yet when I play it, it seems to partially mimic the video in the second screenshot; it "extends" to 2:41, and it plays the video from the second video. However, it plays the audio from the first video and the progress bar still only goes to 2:30, yet the video keeps playing for another 11 seconds without any audio until the video from the second video ends. Seeking forward causes the different recommendations to pop up as if the video had ended normally.

I am using a MSI laptop on Windows 10. I have restarted my computer, cleared my cookies and cache, and updated Firefox to the latest version. This problem persists with all of my extensions disabled, and when logged in or out of YouTube (no matter the account) or in incognito mode. At first, I thought it had something to do with the video and/or channel, since the other video with the same problem was also uploaded by AmericanDadVEVO. When I tried watching the video in the first screenshot on Microsoft Edge (which I barely use and have no extensions on), however, it worked normally.

Any help would be appreciated! I really do not want to switch to another browser.

You can try to disable hardware acceleration in Firefox.

Close and restart Firefox after modifying the setting to make changes effective.

You can check if there is an update for your graphics display driver and check for hardware acceleration related issues.

I did both of those things, and I'm still having the problem.

Hello? You haven't responded in a couple days. I noticed you replied to baums547's post a second time shortly after I posted my reply on this thread. Could I get some further assistance, please?
