mysql57-(server/client) 5.7.34 does not work correctly

Hello.
Update mysql 5.7.34 does not work correctly, it creates a heavy load on the server.
Software in the system is updated.

100% CPU load from mysqld after upgrade.
With mysql 5.7.33, the processor load is minimal, maximum 2 processor cores.
With mysql 5.7.34, the load is 100% of the processor on all 8 cores.
MY CPU CPU: Intel(R) Xeon(R) CPU E3-1270 v6 @ 3.80GHz (3792.19-MHz K8-class CPU).

Web cms bitrix.
I had to roll back to the previous version mysql 5.7.33.
My system FreeBSD 12.2-RELEASE-p7 amd64.
There are no errors in the mysql log.
There are no errors in the messages system log.
What to do, what to do ?!

My mysql config file.
