Altium 19 CRASH

[Lucky-Luka]

Hi all
After I've completed the schematic I've compiled it and then i've selected the voice UPDATE PCB DOCUMENT under TOOLS.
Then EXECUTE CHANGES.
After all the green ticks have appeared the program crashed. I've tried to shut down the PC and turn on it again but the same thing happened again.
Is it my program or is there something wrong in the files of the project?
I attach a picture of the crash. The program freezes and I cannot even click on the "send and close" button.
Can anyone check the attached file?

Hi,
do you have latest update of Altium 19? Can't try with Altium 20?

Hi Lucky-Luka I've tried your files and got no error.
This crashes are something that sometimes just happens, my best suggestion, restart everything, both Altium and PC.

I've downloaded an Altium 21 trial version.
The problem is gone. I still would like to know why I had that problem...
