Project's workspace getting empty after I start to use v2019.2

Hi there

I've been using this nice tool since 2017 and I didn't have any problem before when upgrading to a new version.

I use to work in my project in two different places (and PCs), but keeping the project in a memory-stick. I was using one of these PCs and I choose the update option when it appeared - moving from v2019.1 to v2019.2 - and it seemed everything was OK and I continued to work on my project.

Then, I started to work in the other PC and - again - Intellij was updated.

The problem is that now, every time I switch between the PC's, the "workspace.xml"  under may project folder is "cleaned" and I get a empty IDE!

I took a look inside the "workspace.xml" under my project folder and it was now only 8KB instead of the old 44KB (my backup).

I also looked at the IdeaIC2019.2 folder and noticed there is now under "config" a directory named "workspace" and inside of it I found some files named like this 1OhHjs8Mw3c206xwSUWGMlF8PXE.xml.

If I deleted all .xml files under "C:\Users\USER\.IdeaIC2019.2\config\workspace" folder and I restored my "workspace.xml" into my project's folder "F:\Intellij Projects\Curves\.idea"  and then I can start the IDE and get my project opened properly and using the layout and files I was working before.

It's becoming annoying have to repeat this process each time I'm going to work on my project.

So, does someone has any idea about what I can do to fix this behaviour?

Thanks in advanced
