Crashes after few hours of working ok

[Plampi64]

After HA 2022.8.x updates worked fine. Now etrv2mqtt crashes after few hours of operation. I can start it again and then it will again working few hours until again crashes. Log on crash looks like this:

In addition, Watchdog -function does not restart service as it should after crash. Have to start it manually.
