This mostly happens when you use youtube while being logged into a google account.
I fixed this by using firefox containers + https://addons.mozilla.org/en-US/firefox/addon/switch-container/

• logout from google / clear cookies.
• switch to a new “google” container and login to see your subscrpitions
• if a video doesn’t load switch to decontained

also has the nice benefit of not messing up your reccomendations when clicking on random yt-links from other sites

There’s an app for that: https://github.com/zacharee/Tweaker

You’ll need to use adb to grant special permissions that an app can’t request on its own.

adb shell pm grant com.zacharee1.systemuituner android.permission.WRITE_SECURE_SETTINGS
adb shell pm grant com.zacharee1.systemuituner android.permission.PACKAGE_USAGE_STATS
adb shell pm grant com.zacharee1.systemuituner android.permission.DUMP
