Safari App extension getting removed from extension list

Hello,

with Safari version 14.0.1, it is observed that sometimes the Safari App extension is getting removed(it is not present in the list) randomly.
On restarting the host app, it is getting added again, but it gets removed after sometime. Not seeing any crash or any console message.

Any one else seeing this issue.
