after running for a period of time, a similar exception will be reported, causing Kafka to crash. How to completely resolve this exception?

Answer 1

If you have to use kafka in windows environment. You have to disable log retention.
In Kafka server.properties
log.retention.hours=-1
log.cleaner.enable=false
# Remove any other rows start from log.retention.*

Answer 2

To run Kafka on Windows it's recommended to do so using WSL2 as detailed here. Otherwise you encounter the kind of problems described above.
