Server 2019 + IIS 10 + MySQL 8.0 + PHP 7.2
I've got an error about the default email template of internal activity alert. The variable note.message is not valid. Please see below. I've not change any in this template.
My SQL version 8+ is not officially supported. The awesome people that built this are still working on that. You might run into some issues, however I have seen that bug in my installation as well yet it does display the correct message.
I do not see any errors in your post. I see a warning about a variable. It simply says it may not be valid.

We do support MySQL 8+, in fact, it's recommended as it includes updates to things like auto_index storage, etc.
auto_index
Cheers.
