Recycle Bin crash issue #38
Description
Good evening. We encountered an issue in production. We enabled the recycle bin in production, but it crashed when an operator accidentally deleted a database and used the recycle bin function. We found that it seems to crash immediately when restoring more than 20 tables at once. Initially, it worked fine during our tests, probably because we were only testing with a few tables. Below is the process of reproducing the issue.
