After upgrade to 10.7.3-1 with enabled data-at-rest encryption unable to restore dump file.

After an upgrade from 10.6.7 to 10.7.3 we have attempted to export and import a dump. This fails on import with errors like "ERROR 2013 (HY000) at line 13654: Lost connection to server during query". The mariadb crashed on import (error log attached). We than upgraded to 10.7.4 and the import fails too.

This issue has only manifested with data-at-rest encryption enabled and key checks settings in dump file on an table with more than 58254 table rows (example dump attached).

Data at rest encryption was enabled with:

File Key Management

plugin_load_add = file_key_management

file_key_management_filename = /etc/mysql/enc/keys.enc

file_key_management_filekey = FILE:/etc/mysql/enc/.key

file_key_management_encryption_algorithm = aes_cbc

InnoDB/XtraDB Encryption

encrypt_binlog            = ON

encrypt_tmp_disk_tables   = ON

encrypt_tmp_files         = ON

innodb_encrypt_log        = ON

innodb_encrypt_tables     = ON
