I play the Java Edition and version 1.16.1 on the PC. When I hit a sword, it has to "recharge" first. Do you know what I mean? How can I remove this? It totally annoys me. Or can you delete the new version and play an older version in which it wasn't?
Yes, that's because of the new version. If you want to play cooldown without a sword you have to go to an older version. But then there are not all the new things like e.g. Bees
With version 1.9-1.16.1 the PVP system is unfortunately so bad.
Play the 1.8 versions that have the normal PVP system without "charging".
That is in the new versions. The latest version where the swords don't have a cooldown is 1.8.9, but you don't have all the new features.
Can you tell me how I can switch to an old version

In the Minecraft Launcher, select Installations → New → Version, in this case 1.8.9 → Name if you want → Create. Then you have to choose the installation and click on Play.
