Crash while creating new tag

Good Morning.

I'm using Step7 and Wincc Professional V13 SP1

I've a project with a S7-300 plc connected to a TP1200 Comfort panel.

I have already created some pages and tag into the hmi without problem and everything was working fine.

Today i've just open my project to implement some new features. Now when i try to add new tag exploring the plc blocks just after clicked on one of the blocks, the software crash.

This issue happen only when i'm trying to add the tag directly from the object in the page. Instead when i add tags in the HMI Variable tables, everything works fine.

I've already done a software compile without errors(plc and panel). But nothing changed

Any suggestions?

Hi

In the window where you explore PLC block, you must change sequence of columns to default view. The first column is blue tag, next column is name of tag, third is Data type. I think that this should help.

Best regards
