Daily log errors, website crashes with ryviu

Hi!

I installed ryviu on a website.
And I went to update some plugins and the site was out and wouldn’t come back…

I went to consult the log file and there were numerous records of ryviu errors… I just deactivated the plugin via ftp and the site came back to work normally as if by magic.

Seems to have a serious problem with it, can you check that?

See in the log:

I have these daily logs recorded since 03/11/22 which I believe was the day I installed it.

It seems like a recurring problem.

Can you check what it is?
