Take React off your Resume entirely, that way you should be able to filter out the jobs you won't get anyway, and you should be able to say no to any online test that requires React.

I'd also look again at the type of companies you're applying to. Insurance companies, banks, pharma, government agencies - Enterprise software basically - these tend not to be using the most cutting edge front end frameworks.

Also, if you have even a small amount of experience in Enterprise type backend technologies you should be able to land a backend or full stack role at one of these types of companies. .Net, Java, etc.
