MySQL continua travando, banco de dados corrompido?

mysql Ver 8.0.20-0ubuntu0.19.10.1 para Linux em armv7l ((Ubuntu))

MySQL continua travando. Receio que o banco de dados tenha sido corrompido.

Ele trava após uma consulta simples.

mysql> select count(*) from all_values;
ERROR 2013 (HY000): Lost connection to MySQL server during query

Ao tentar fazer backup do meu banco de dados, ele falha:

$ mysqldump -u root -p tsl > tsl-bu4.sql
Enter password:
mysqldump: Error 2013: Lost connection to MySQL server during query when dumping table `all_values` at row: 3835117

Isso é consistente, falha sempre na linha 3835117.

Configuração atual:

[mysqld]
log_error = /var/log/mysql/error.log
general_log = on
general_log_file=/var/log/mysql/general.log

innodb_force_recovery = 0
innodb_buffer_pool_size=1G

Eu tentei de tudo com innodb_force_recovery definido para todos os valores (1-6) e também tentei vários valores para innodb_buffer_pool_size, mas sem diferença alguma.

Questões:

Presumo que isso significa que meu banco de dados está de alguma forma corrompido. Essa suposição está correta?

Como parece falhar sempre na mesma linha, isso significa que identifiquei a linha que está corrompida? Em caso afirmativo, existe uma maneira de remover apenas esta linha (sem usar uma consulta SQL que obviamente fará o MySQL travar)?

Desde já, obrigado. E sim, começarei a fazer backup do meu banco de dados regularmente a partir de agora.
