Version Used:
VS 2019 v16.7.3
Recently repaired to see whether that fixed the issue. It did not.

Steps to Reproduce:

1. Create a new VB.NET project in a path that contains a number within parentheses. ie: E:\VBProject (x64)\BadErrorPath
2. Write a line of code that has an error in it. ie: asdf
3. Verify that the Error List window shows the Line, Col, Path, and Source columns.
4. Close the code window.
5. Build the project.

Expected Behavior:
Expected the Error List to show the correct path, line, and column for the error.
Expected to be able to double-click the build error line to open the file with the error, positioned to the error line.

Actual Behavior:
I get two errors, The one from the Build source says line 1, column 1 and has a bad path. Double-clicking it does nothing.

The whole build output is below and in it I see:
E:\VBProject (x64,9)\BadErrorPath\Module1.vb(4): error BC30451: 'asdf' is not declared. It may be inaccessible due to its protection level.

It looks like the (x64) from the path is tricking error reporting into placing the column number in those parentheses rather than after the line number in (4).
