[boomacoh]

Application Version

3.5.0
Platform

Windows 10
Printer

Tevo Tornado 2018
Steps to Reproduce

1. Reboot/Shutdown Windows
2. Reopen Cura 3.5.0.
   Actual Results

No loading screen is shown when Cura is Launched.
A new instance of "cura.exe" is being added to task manager whenever launched.
Need to uninstall and install just to open cura.
Expected results

Even after rebooting or shutting windows down Cura should still be able to launch properly.
Additional Information

Cura 3.4.1 works perfectly even after a shutdown and reboot. I only noticed this bug or issue when I upgraded to 3.5.0
Already tried running it as administrator and still same results.

Can you please send the log file to us? You can find it in your user data folder (in C:\Users\\<your username>\AppData\Roaming\cura\<Cura version>\cura.log. Let's see if there is something there that indicates the problem.

cura.log
Here you go.
When I tried reopening it just gets stuck on last line
"2018-10-16 15:53:03,209 - DEBUG - [MainThread] CuraEngineBackend.CuraEngineBackend._terminate [294]: Attempting to kill the engine process"

[alekseisasin]

Hi @boomacoh ,
''....Attempting to kill the engine process" - It is fine, it is expected the message.
There is another error while saving the Gcode, Can try start Cura and close without doing any operations, reboot Windows and try to start Cura again.

Can you describe the steps you did to save the Gcode file, especially file location?

I just did what you suggested in that post. Disabling the Send (anonymous) print information. Which solve the problem. Even when I turn it back on. It is still able to launch properly now. But I'll still be on watch and check if it comes back.

Thanks

Note that these are errors that we catch and log, but are handled otherwise. The fact that they show up in the log doesn't
that it's the actual cause of your issue.

[diegopradogesto]

Yes, this is not the solution, but at least is a workaround for the user. It can be something with your network configuration, firewall, ... If you have more info, maybe we can go deeper.

Thanks for sharing your results.

[boomacoh]

Unfortunately this didn't solve it entirely. I get to relaunch Cura even after closing it if has not yet been used that much after reboot. Which is why I thought your solution worked. Now after some hours of using it, it went back to the issue again. Even uninstall my python on my pc and also tried using 3.5.1 but nothing is working now. I just constantly uninstall and install just to use it.
I'll be posting the new log again if in case it can help. Any other information you need to solve this just let me know.

Thanks!

@boomacoh , I wonder, when you have the situation that you cannot start Cura. Can you open the
_C:\Users\\AppData\Roaming\cura<Cura version>_ folder and check, do you have a cura.lock file there or not?

[boomacoh]

There is no cura.lock file in the directory you mentioned

[Chucky911]

I had the same issue as you....here is how i solved it:
Open Windows Defender->Virus & Threat Protection settings->Exclusions-> add or remove exclusion

Click Add an Exclusion and select "Process"
Enter process name: Cura.exe

launch Cura

Let me know if this works for you !

Sorry only now, but this is working for me. Had to test for a couple of days before I gave some feedback, so far I am able to open Cura after reboot or when I accidentaly close it.

Thank you!

[diegopradogesto]

This issue seems to be solved by adding an exception to Windows Defender. However we are keeping an eye on this because it happens every so often and could be related with other libraries that are used in Cura.

Thanks for the effort on tracking the issue.
