Catalina ran an automatic update to 10.15.4 and this dialog appeared upon restart:

Thank you for the report.
But I’m Takuya Matsuyama, not Fumihiko Takayama.
Inkdrop does not have any macOS system extensions.
I’m on 10.15.4 and it works fine.
So, I guess it is caused by an other software made by Fumihiko.

I think this is probably coming from the Karabiner-Elements app installed on your machine.

Yes, thank you.
