I am compiling legacy code, and running into errors 8284 and 6633, as many others have as well. This is 40 year old code, and I have 559 of these errors, so editing the source code is not an option. I see on the forum that in V12, it was possible to turn off these errors by setting Properties/Fortran/Diagnostics/Check Routine Interfaces to "No" (the default, I guess, used to be "Yes".
In V18 (at least as installed on my system), the default is already "No", so there is nothing to disable to get this to compile and link. Has this option moved in later versions?
The property page may have the Check Routine Interfaces option set to No, but something else is turning it on as your compiles all have /warn:interfaces in the command line. Check the Fortran > Command Line page. If nothing helps, please ZIP the .vfproj file and attach it here.
The screenshot is for the Release configuration, and your buildlog is from building in the Debug configuration.
By default, the Debug configuration has all diagnostics and (most of) the run-time checks enabled.
