ArcGIS Pro 3.3 workspace will not open in ArcGIS Pro 3.4

[PWhitten]

I have a workspace that I can open an edit with ArcGIS Pro 3.3 but causes ArcGIS Pro 3.4 to crash.  I have verified that I can open the file on other computers that haven't upgraded to version 3.4, and, I have verified that the version 3.4 can open other files.  I have looked at the change log for ArcGIS Pro 3.4 and can't see anything that should trigger a crash.  Any suggestions on how to fix or work out the problem?

I have similar problem. I get the error below

I got the "parameter is incorrect" error too, and just discovered that "folder connections" in my Catalog window were bad (i.e. they didn't upgrade properly from 3.3?). What I needed to do was create a new folder connection ("Add folder connection") and then the feature classes in my gdb were visible and could be loaded.

I too am getting the "The Parameter is Incorrect" error, after upgrading to 3.4.  After the upgrade if I try to open any FGD on any folder connection that was save in a project, I will get the error.  If I remove and replace the folder connection it works correctly.  After saving and reopening that same project, I get the error again. 

I tested with a band new project as well.  I added the folder connection and I could open the FGD.  I saved the project.  Opened the project and tried to open the same FGD and get the error.

My solution was to uninstall 3.4 and reinstall 3.3.  Everything seems to be working fine now.  Hopefully they fix the issue so I can upgrade to 3.5.

Same. When I used 3.4 to open projects created by 3.3, it would crash. very frequently.

I'm having the same issues when trying to open geodatabases that I've been using for years. They worked in the same ArcGIS Pro project I was using in 3.3. Now, in 3.4, I'm getting the "The Parameter is Incorrect" error as posted above.

Disconnecting the existing folder connection and Redoing the "Add Folder Connection" worked for me.
