Broken information_schema on Aurora MySQL 8.0 3.06

I hope someone has some ideas on how to resolve the following issue I'm facing.

Here's the setup:

• 8.0.mysql_aurora.3.06.0 cluster with a writer and a reader instance(db.r7g.large)
• PHP web application using a database on the cluster(~2GB) using the DB reader endpoint
• another PHP application which refreshes some of the tables with a total of ~5mil rows via the DB writer endpoint, using:

INSERT INTO :tmpTableName VALUES (value1, value2, value3, ...);
RENAME TABLE :tableName TO :oldTableName, :tmpTableName TO :tableName;
DROP TABLE :oldTableName;

Unfortunately after the refresh PHP app finishes, we get the following error on the DB reader:

SQLSTATE[42S02]: Base table or view not found: 1146 Table 'database.table' doesn't exist.

while the table is fully functional on the DB writer.

The error disappears after DB reader reboot.

Any help will be greatly appreciated!
