Only 0.04% of Ethereum validators have been slashed since 2020, says core dev By Cointelegraph

The ecosystem has seen only 226 validators slashed since the launch of the Beacon Chain on Dec. 1, 2020 — amounting to just 0.04% of 524,060 validators, according to an Ethereum core developer.

Slashing is a process where a validator breaches the proof-of-stake consensus rules, which often results in the removal of that validator from the network and slashing a portion of the staked Ether (ETH) that the validator provided as collateral.
