Do you get the error message similar to the following?

The cypress npm package is installed, but the Cypress binary is missing.
We expected the binary to be installed here: /xxx/.cache/Cypress/4.8.0/Cypress/Cypress
Reasons it may be missing:
- You're caching 'node_modules' but are not caching this path: /xxx/.cache/Cypress
- You ran 'npm install' at an earlier build step but did not persist: /root/.cache/Cypress
Properly caching the binary will fix this error and avoid downloading and unzipping Cypress.
Alternatively, you can run 'cypress install' to download the binary again.

If so, according to the error log, it provides a workaround to this problem. You can try to run the cypress install command again to fix the problem. Here is a case you can refer to.

In addition, the quotation mark of “$(Agent.OS)” should be like "$(Agent.OS)". Or you can choose to run the jobs in self-hosted agent, machine-level caches and configuration persist from run to run, which can boost speed.
