It is weird that there is no
wp_posts table present in your
bitnami_wordpress database. Did you modify anything in your MySQL database before having this issue?

I also double checked that this table exists running the command below. Could you please run it and send us the output? You have to use again the randomly generated password for the user
bn_wordpress in the
mysql -u bn_wordpress -p bitnami_wordpress -e "show tables;"
Also see below the output I get after running that command:
