MSB4018 horror (not a simple error)

Guglielmo Cancelli 5

I would like to report that for a few days now, even when creating a new empty VB solution with only the default form, when I try to compile I always get MSB4018, which obviously doesn't make any sense, being the default project.

I tried repairing the VS2022 installation but that did not change the result. Not even running InstallCleanup and then performing a clean re-installation changed anything.

A few days earlier I had done an update of VS.

In short, I can no longer code! 🤬

I'm using win10

Sorry, what do you mean by "what task"?

The MSB4018 error should mention the task and other details:

This is the integral error I receive.

However, I noticed that if I create a new project on disk C the error does not occur. I get this error from projects created on the Google synchronized folder. But only in this last week, it was working before.

I have no alternative to using Drive, so how can I solve it?

To my knowledge there are no other processes that use those files, unless GDrive in the last week decided to keep those files open all the time.

I have already tried shutting down and turning back on, the problem remains.

Hi @Guglielmo Cancelli ,

Did you open some files but didn’t close them before this issue appeared?

Do you still remember what you have done before this error appeared?

Have you tried to create and save a new project to another newly created clean folder on GDrive?

I have the same problem since a few days.
New empty C# solution in VS2022: compilation terminates with error MSB4018 in a Google synchronized folder (also in a new folder) but works fine on any other local not syncronized folder.

Also, there is desktop.ini file (I hadn't this before) with the following content:
[.ShellClassInfo]

ConfirmFileOp=0

IconResource=C:\Program Files\Google\Drive File Stream\84.0.4.0\GoogleDriveFS.exe,25

Hello @Guglielmo Cancelli ,

Welcome to Microsoft Q&A forum.

Please try following to clean some cache files and fix any corrupted files first.

Run CMD as administrator, run DISM.exe /Online /Cleanup-image /Restorehealth command, wait for it finishes running, run sfc /scannow command.

Navigate to C:\Users\{username}\AppData\Local\Microsoft\VisualStudio\17.0_XXXXXXXX folder, rename this folder.

Reboot your machine and rename %Temp% folder(C:\Users\{username}\AppData\Local\Temp).

Update Windows OS and make sure that there’s no Windows Update Errors.

Launch VS as administrator, create a new project and check again.

Besides, do you have full permissions on your machine(please check following: antivirus, group policy, permission limitations)? Does running VS as administrator work?

If there are more detailed error messages, please share them with us to check further.

Best Regards,

Tianyu

Hi @Guglielmo Cancelli ,

Is there any file(on the Google synchronized folder) opened or used by other processes? If so, please try to close them and test again.

Please try to close all tabs(in VS > click "Window" > "Close All Tabs") and rebuild your project.

Besides, have you tried to reboot your machine and check again? Is it possible to try to disconnect and then reconnect to that folder?

Hi @Anna Schmalzl ,

Could you confirm that whether this issue appeared after you updated VS 2022?

If this issue appeared after you updated VS 2022, please try to rename C:\Users\username\AppData\Local\Microsoft\VisualStudio\17.0_XXXXXXXX folder and check again. If the same error still appears, please try to roll back VS 2022 temporarily and directly submit a feedback ticket on our Developer Community for further investigate. After you submitting the ticket, please share us the ticket link for tracking and better help.

Kind Regards,

Tianyu

Hi Tianyu,

I renamed the folder C:\Users\username\AppData\Local\Microsoft\VisualStudio\17.0_XXXXXXXX but the error remain still the same.
I do not have an option to roll back latest update, because I tried a new installation of Visual Studio Enterprise 2022 (17.8.2).

Best Regards
Anna

p.s. After update to version 17.8.3. the error reamins the same.

Hi Anna,

In case this issue is caused by the update and you have been blocked for a long time, you can try to directly install and use a previous version of VS Enterprise 2022 temporarily. Here's the link: Fixed version bootstrappers.

BTW, if you do submit a ticket on our Developer Community, please share us the link for better tracking,

Kind Regards,

Tianyu

Hi Tianyu,

I installed VS 2022 Enterprise version 17.6.10 and now it works again in Google synchronized folder.
Problems starts with version 17.8.x.
