Since updating to the latest version, some issues have arisen.

1. The first issue is that after the update, there are errors with the joint functionality, although the components have not been rigidly assembled.

2.After encountering this issue, I reinstalled the software, but now I can't open the files. It seems like the version has been rolled back unintentionally？

I had the same issue (#2) with not being able to open files.  Their was a release that caused issues that they blocked as it was causing issues.  I don't know what the issues were and if they are related to what you were seeing.

There is another post with the subject "Project not opening after most recent update" that has updates from Autodesk that they were pushing out a new release that would fix this.  I don't know when you updated/checked, but I did a check this morning about 40 minutes ago and there is a new release that fixed the problem.

As I understand it, 2.0.19204 was the problem version.  The current version I just upgraded to is 2.0.19207 and it is able to open documents saved with 2.0.19204.

I had this issue because I updated my laptop while I was working on something at the library, but my home PC couldn't open it when I got home.
