Playground Link

https://typescript-eslint.io/play/#ts=5.3.3&fileType=.tsx&code=FAYwNghgzlAEBiB7RsDexawA4CcCWAbhAC4CmsEIIpMiOFVsAvLAMwDcwGD1t9AxJRDNYAFk4BfIA&eslintrc=N4KABGBEBOCuA2BTAzpAXGUEKQAIBcBPABxQGNoBLY-AWhXkoDt8B6Y6RAM0Wls4CGAEwD2TeIXRRe0EdEjgwAXxBKgA&tsconfig=N4KABGBEDGD2C2AHAlgGwKYCcDyiAuysAdgM6QBcYoEEkJemy0eAcgK6qoDCAFutAGsylBm3TgwAXxCSgA&tokens=false

Repro Code

classFoo{private accessoracc=3;  accessor #acc=4;}

ESLint Config

module.exports={"rules":{"@typescript-eslint/prefer-readonly":"error"}};

tsconfig

{"compilerOptions": {"strictNullChecks":true  }}

Expected Result

Accessors should be ignored byprefer-readonly as they cannot be marked asreadonly.

Actual Result

A broken fix is done that addsreadonly to the accessors:

classFoo{private accessorreadonlyacc=3;  accessorreadonly #acc=4;}

Additional Info

I will make a PR for this.
