The modules are not displayed in the development tools

Hello, I would like to know if someone from the community had the same thing and how I resolve it.
The following happens, the modules are not shown in the SuiteCRM development tools, I check the .log files but none inform me of the error. :S

SuiteCRM: 7.8.19
Sugar version: 6.5.25
Using the IIS Administrator
Operating system: Windows Server 2012 R2
php: 5.6.36

Which screen is that, exactly? Module builder, initial view?

Check also your Browser’s Developer console for errors.

And try a different browser.

Then tell us what you found out. Thanks

Thank you very much. I will check the browser’s developer console to detect errors which is what may be happening.

The image I send is when I enter the studio, the same thing happens in the module’s constructor.

Thank you very much “pgr”, I was able to solve it, I opened the browser console and it showed me that there were errors: SyntaxError: illegal character
I solved them, I can see the modules in the development tools
