cy.session failure that didn't come from my code

Current behavior

I got this failure once. Unfortunately it did not fail the second time, so it is not easily repeatable.

As far as I can tell, the failure came from within cypress, and not from my code.

Test code to reproduce

Here is a snippet of my test:

    cy.session([email, sessionCacheId], () => {
      cy.visit(this.url);

      cy.origin(
        this.b2cSigninUrl,
        { args: { email, password }},
        // eslint-disable-next-line @typescript-eslint/no-shadow
        ({ email, password }) => {
          cy.url().should('match', new RegExp(`^${Cypress.env('b2cHostUrl')}`));

          cy.get('[id="signInName"]').clear();
          cy.get('[id="signInName"]').type(email);

          cy.get('[id="password"]').clear();
          cy.get('[id="password"]').type(password);

          cy.get('[id="next"]').click();
        });

      cy.url().should('match', new RegExp(`^${this.url}`));
      cy.url().should('not.contain', '/id/signin');

      cy.window().then((win) => {
        // ensure selected tenant is not cached in session
        win.sessionStorage.removeItem(this.tenantStorageKey);
      });
    }, {
      cacheAcrossSpecs: true
    });

This is being thrown from this piece of code: https://github.com/cypress-io/cypress/blob/develop/packages/driver/src/cy/commands/sessions/index.ts#L435

I haven't seen this error before, I bet it is a timing thing.

This may be similar to #25550.
However, that issue was closed, and I can't tell if there were any changes made.
