ERROR: venusq: A critical error has occurred. Please re-run the Monkey C Compiler with logging enabled and file a report with the Connect IQ support team ([email protected]).

For anyone looking back on this forum with the same issue, I was able to kinda fix the problem. Here are some bullet point tips I would go through until something worked:

- When choosing a directory to save the debug build, make it the auto folder the computer prompts you to save in.

- If the prompted folder still gives issues, try the last folder you saved a debug build in. (if you don't want to rewrite the old build, put the old one in a new folder first -- sometimes I had no choice but to rewrite on the old build)

- Unforchantly, you may have to start a new project. When you do, copy/paste old lines one by one (or chunk by chunk), and every time your project is in a runnable state try to run a simulation. (one issue I had was a new error found in a line that wasn't detected in the last project -- even though the simulation ran perfectly in the old project)

Overall, I think this issue starts happening when you make more than one build (with slight differences) and/or start saving the builds in different folders. This issue is very annoying because even when you comment out recent changes so it's in a state that worked previously, the error still appears. Practically forcing you to re-do everything and delay the debugging process.

Hopefully, someone in Garmin sees this post and tries to address the issue.

Best of luck

idk if this helps, but I think:

- "Build Current Project" is meant for simulator builds (and is equivalent to what happens when you Run a project that needs to be built). In this case you're not even able to choose an output folder

- "Build For Device" is meant for sideloads (and in this case you're prompted for an output folder - typically I choose a folder that's different from the default of bin\)

YMMV. In another post, someone fixed their build issues by selecting "Delete All Apps" in the simulator.

8649264, if you can still reproduce this can you run the compiler again using the --debug-log-level and --debug-log-output options and email the output to [email protected]? This will help us determine why it wasn't building and allow us to fix the problem.

--debug-log-level  <arg>  Debug logging verbosity [0=errors, 1=basic,
                          2=intermediate, 3=verbose]
--debug-log-output <arg>  Output log zip file

I just encountered this kind of error, because my project name has Chinese characters, change to English will be fine. I hope it helps

2753589 Are there specific Chinese characters in the project name that were causing a problem? We haven't been able to reproduce so far, so if you have additional information that might be helpful, we'd appreciate it!

I had same problem because of exclamation mark in path of project folder (!)

Kyle.ConnectIQ Brandon.ConnectIQ I also got this error message, so I wanted to do the build with the debug enabled, but there are 2 issues:

1. I'm not sure if VSC or the Monkey C plugin writes this to the terminal when I build, but it would be useful if the parameters that contain spaces would be either escaped or put in double quotes, so we can copy&paste it and use it. In my case the stupid Mac folders include a space:

Executing task: java -Xms1g -Dfile.encoding=UTF-8 -Dapple.awt.UIElement=true -jar /Users/me/Library/Application Support/Garmin/ConnectIQ/Sdks/connectiq-sdk-mac-6.4.2-2024-01-04-a1dd13ee0/bin/monkeybrains.jar -o bin/MyDataField.prg -f /Users/me/MyDataField/monkey.jungle;/Users/me/MyDataField/barrels.jungle -y /Users/me/garmin_developer_key.der -d epix2pro42mm_sim -w

2. The bigger problem is that when I copy&paste it to a terminal (and fix the space issue) then I get an error:

ERROR: The private key was not specified. Use command line option: -y.

This would be bad enough just for the fact that I just copy&pasted it and I expect it to work as is. But it's even worse that the error message doesn't make sense, as the command already includes: -y /Users/me/garmin_developer_key.der

Please advise

not sure what shell macos uses, did you tried like this? :

"/Users/me/Library/Application\ Support/Garmin/ConnectIQ/Sdks/connectiq-sdk-mac-6.4.2-2024-01-04-a1dd13ee0/bin/monkeybrains.jar"

or 

/Users/me/Library/Application\\ Support/Garmin/ConnectIQ/Sdks/connectiq-sdk-mac-6.4.2-2024-01-04-a1dd13ee0/bin/monkeybrains.jar

maybe tripple backslash

You didn't get my point. I added the backslash myself. My problem is that it doesn't compile because:
ERROR: The private key was not specified. Use command line option: -y.
