Luckily I don't have such problems but I suppose that "
Native Lazy Tabs":

Thank You.
"Automatically discards all tabs at startup, before they load, reducing memory footprint and unnecessary bandwidth usage.
Native Lazy Tabs is a light extension for users that don't want to load all tabs when Chrome is started. It's native because it uses the native tab discarding method from the Google API (introduced in version 54). Also, because of that, it doesn't have the shortcomings of older implementations that could cause bugs like the pages reloading itself even after suspended."
