Error trying to create a Security Provider

Hello,
I’m trying to build a new app and I tried for several times to add a new Security Provider, but it appears this error message and doesn’t allow me to do it. Can you help me, please?

Try restarting Wappler and create the security provider again.

I closed wappler and logged out . Then I logged in again and still appears the same error.

Where is your project folder located and do you have write permissions there?

I created a folder in my computer for the wappler projects. Then I created a subfolder for this project. I’m the only user of the computer.

I made some test apps before and I created subfolders in the same place and I tried adding Security Providers, with no errors. Only in this one.
