【VSCODE extension】Failed to launch the app: Timeout

This was happening to me. I saw that new files was copied to  %TEMP%\GARMIN\APPS folder but the name was truncated. I changed the workspace folder name to remove the space it had and it started working (worskspace folder is sued to name the prg file).

TL;DR: check if your workspace folder name has a space and remove it.

I was having the same issue and noticed that a new files was always created in that folder but the name was truncated. The solution for me was to change the workspace folder name and remove the space it had. It seems that when the file is copied to the TEMP folder they are not checking for spaces or using "" around the file name.

TL;DR: check if your workspace folder has a space in the name and remove it.

Yep, same for me.

Is this something that you can reproduce with any app, or is it an issue with just this one app?

Have you tried running the shown command at the command line? Does that show any errors?

all apps have this problem,create new project, SDK samples,and my project create before

I try running the shown command at the command line, no errors.
