tapeberlin on ""Opening Hours" Error 2037"

Hello thanks to "janizde" for the plugin.

I can`t get it to run neither to access the options.
I can activate it but then I get the error "2037"

I am using a custom theme and woocommerce - all on a local server.
Already tried to deactivate all plugins to see if one is causing the problem.

Thank you & greetings
george
