Description of the problem
CSB's version of ESLint complains about the line
foo.bar?.()
with "Expected an assignment or function call and instead saw an expression."
Testing the same line with the latest version of ESLint shows no warning or error, also I think there is no logical reason to show the warning.

Research direction
Start by reproducing the warning in the linked CodeSandbox and ESLint playground, then locate the project ESLint configuration and version responsible. Confirm which configuration produces the optional-chaining warning; done means the reported line no longer triggers an incorrect warning without changing the other lint rules.
