System.IO.PathTooLongException - VS2022

[MariusEls]

I recently installed VS2022 and attempted to build a solution that currently builds successful in VS2019, and got the below error:

This is an unhandled exception in MSBuild -- PLEASE UPVOTE AN EXISTING ISSUE OR FILE A NEW ONE AT https://aka.ms/msbuild/unhandled.

Using

• MSBuild version 17.5.1+f6fdcf537 for .NET Framework
• VS Professional 2022 (64-bit) version 17.5.3

Not too sure why this issue is creeping back into MSBuild as I'm sure it was resolved in VS 2019

Just to confirm: Are you building from the same directory path in VS2022 as you did in VS2019? Do you still have VS2019 installed? The same solution on the same machine in the same directory path builds successfully in VS2019 and fails in VS2022?

Good afternoon

Are you building from the same directory path in VS2022 as you did in VS2019? Yes

Do you still have VS2019 installed? Yes

The same solution on the same machine in the same directory path builds successfully in VS2019 and fails in VS2022? Yes

Thank you and Regards
