I got the error at line 44.

You can update the code, even the debugger is running and test it again without redeploying the Dll in the Plugin Registration Tool.

Test it thoroughly and update the Dll in the Plugin Registration Tool, once everything is working as expected.

Hope you have followed all the steps and tested the plugin code successfully.
