I was surprised to not see any recent posts on this.
While using Pro 2.7 I am having to kill the program in task mgr after it freezes on save. This happens when using local data, and with data in Agol and is not correlated with any other action I know of.
Pretty disruptive since it results in loosing all project work up to hitting save button.
The program creates recovery project when it's been killed in task mgr, it rarely has the work saved in the recovery file.
May start by reinstalling.............
So, a reinstall of 2.7 did not help with program freezes. I rolled back to 2.6 and wow am I getting some strange behavior all over, errors opening layers, opening field view for tables, editing.
I have also noticed this issue as of 2.6/2.7. I went through the same process of uninstalling the program and reinstalling, and the problem continues.
In an active ArcGIS Pro Project File, I will click save, the save occurs, and then when I try to close the Project File, clicking the red X does nothing. Program remains open. Sometimes I can navigate to Project> Exit and that will execute a close, but not always.
One thing that may help with the freeze on save (believe it or not) is to update your video card drives. Do a search on your PC for Device Manager. In Device Manager, go to Display Adapters and write down the make/model of your video card. Then go directly to the manufacturers website and search/download/install the latest video card driver. What is the result?
I went through the following process prior to posting here: uninstalling the program and reinstalling, updating the GPU driver, adjusting Display/Rendering options, and even increased my system's pagefile.sys size. Regardless of these changes, I continue to notice issues.
