Linker errors and impossibility to debug after visual studio update

Markus Forrer 1

I have run an update of Visual Studio 2019 from version 16.8.3 to 16.9.5. Since then I have big problems!
When building a C++ project (v142) I get a lot of linker warnings:

warning LNK4099: PDB 'XY.pdb' was not found

Debugging the project is no longer possible. I can debug the identical project on another computer on which VS version 16.8.3 is still installed without any problems.
Have others had this experience?

Hi @Markus Forrer , welcome to Microsoft Q&A forum. If you close all VS instances and try to delete the hidden .vs folder, then restart VS and click Build > Rebuild to rebuild your C++ project, will this issue disappear?

Unfortunately no. That was the first things I tried:

git clean (delete all .vs and output folders)

create new clone of the project

Restart VisualStudio (several times)

Reboot computer

Unfortunately all without success.

Hi @Markus Forrer , thank you for your feedback. Please also try to repair VS from VS Installer, and try to create a new project locally(manually) and build, debug to see if this issue also appears for a newly created project, and this will be useful to narrow down this issue.

Hello @Markus Forrer ,

Not sure if the XY.pdb is a system related .pdb file, please also check this document: Configure symbol locations and loading options and try to select Microsoft Symbol Servers option > choose Load all modules, unless exclude then rebuild again.

Best Regards,
Tianyu
