I’m having the same issue on Community Build v25.7.0.110598. Sonar is unable to detect explicit void keyword on functions that return promises.
This sonar rule conflicts with ESLint rule no-floating-promises | TypeScript ESLint
void asyncFunction(); → This errors as a False-Positive, but is a good practice
This issue is related to this topic Typescript '"void" should not be used' triggers wrongly - #5
