VS2019 stops responding
Apr 24th, 2026 at 7:12pm
Print Post  
I've been using VS2019 w/VMicro for a couple years and been very happy with the improvements over the Arduino environment. Recently, I had to reinstall VS2019 and VMicro, and when starting a new extremely simple project ( toggling an LED on a dev board)  the project compiles and programs and executes ok. But when I stop execution, VS2019 stops responding and I have to kill the task and start over.  Any suggestions as to what might be the problem? The Build Log is attached. Thanks

After I wrote the above post, I killed VS2019 to restart it, and then did a compile, which worked ok and collected the Build Log which I attached to the previous post.  But as soon as I tried a Build/Upload VS2019 quit responding.

I killed VS2019 again, and restarted.  The project opened with the default debug point set at void loop().  I removed the default debug point, and did a Build/Upload and it worked ok. 

I stopped the execution, added one line of code '#define Buz2 43', clicked Build/Upload and it locked up again.

Thanks for the reports and logs, we will take a detailed look at this in the coming days.

The Sketch path appears to be on a remote machine in the log, does it have the same issue if you clone the project to a local path and then build/upload?

Here is the sequence I tried. With the solution on the remote drive, I opened VS2019/vMicro and immediately compiled. It worked ok. I added one line of code and recompiled; it locked up. I copied the solution to a local drive and repeated the steps and it did not lock up.

I am having a very similar issue with VS2022.  I can't get through more than one or two edit/compile/upload cycles before VS hangs.  I have already updated both VS2022 and VM to the latest versions.  I'm running on a Dell XPS15 9530 with 64GB RAM and approximately 500GB free SSD space.

lledden - thanks for the update, and we will look into whether better logging is needed when the files are cloned over the network when building, or fi further changes are needed.

FrankP - Can you attach the verbose build output as shown at the top of the page, and if possible a short video or a note of when it hangs would be ideal.

We will keep looking into what could be causing this...

Can you try the release at the top of the below board (26.0422.17) which should resolve the hanging issues in VS2022/VSS2026:

Can you try the latest release in VS2019 as this should resolve all deadlock issues now:-
