ArcGIS Pro Geodatabase Error

[JamesCarroll7]

I have an ArcGIS Pro project which encountered an error when I was trying to create a feature class. 

There is one geodatabase associated with this project. In the Catalog Pane, when I right-click the name of the geodatabase in order to create the feature class, I immediately get an error message that says 'Unspecified error' and this then puts a red exclamation mark beside the name of the project geodatabase (screenshots attached). If I click on the exclamation mark I am able to repair the geodatabase. Doing this removes the exclamation mark and it looks as if everything is okay. 

I am then able to right-click the geodatabase and the 'Create Feature Class' window opens as normal. I enter the name of the feature class and all other details, click 'Finish', but then the name of the feature class goes red and will not create it (screenshot attached). Cancelling this and going back to the Catalog Pane shows the red exclamation mark beside the name of the geodatabase again.

I can go through this process over and over, repairing the geodatabase, trying to create the feature class, the process failing, but it just keeps going in an endless cycle. 

Does anyone know why this is happening or how I might fix it? The geodatabase is saved to my C:Drive and is not shared with anyone. I also have a number of other ArcGIS Pro projects, but this issue is not happening to them, only to this one specific project. Any help is appreciated.

You have blanked out the path to the data.  The gdb should not be saved to a usb drive or OneDrive or other cloud locations.  Punctuation or spaces etc is also a problem.  Try creating the gdb on your local machine (eg C:\data), then create the featureclass there.

If that also fails, then you may have a problem with your installation requiring a soft reset or a complete reinstall of Pro

or a call to Tech Support so that your system and environments can be investigated fully

Thanks for your reply. My geodatabase is saved within my Documents folder on my local C:Drive, I don't use usb drives or clouds for storing them.

I'll try the reset and potentially reinstall. Thanks for your help.

Several Service Packs were just released for ArcGIS Pro 3.3, 3.4. and 3.5 that addressed a BUG where 'locks' on geodatabases were not being removed. This may be causing your issue. To test, have you tried giving the output FC a different name, then renaming the FC afterwords.

Thanks for your reply. Yes I've tried differing feature class names but the same problem occurs each time, the feature class never actually gets created. Bit of a strange problem.

You could try creating a new geodatabase and adding the feature class there. If it works, you can copy the feature classes from the other GDB to the new one, add the new GDB to your project and make it the Default GDB for the project. Then remove the old one.

Thanks for your reply, that's a good suggestion, it looks like I'll probably have to do that.
