I have the same issue.
mysql 8.0
node 18.16
strapi 4.11.4 (4.11.3 is working)

I have the issue with "relatedproducts" in schema:

{
  "kind": "collectionType",
  "collectionName": "products",
  "info": {
    "singularName": "product",
    "pluralName": "products",
    "displayName": "Product",
    "description": ""
  },
  "options": {
    "draftAndPublish": true
  },
  "pluginOptions": {},
  "attributes": {
    "name_de": {
      "type": "string",
      "required": true
    },
    "name_en": {
      "type": "string"
    },
    "orderno": {
      "type": "integer",
      "required": true,
      "unique": true
    },
    "slug_de": {
      "type": "string"
    },
    "slug_en": {
      "type": "string"
    },
    "lexiconarticles": {
      "type": "relation",
      "relation": "manyToMany",
      "target": "api::lexiconarticle.lexiconarticle",
      "mappedBy": "products"
    },
   [...]
    "relatedproducts": {
      "type": "relation",
      "relation": "oneToMany",
      "target": "api::product.product"
    },
    [...]
  }
}

The relation "products" is also not working, but no problem with "related_elxiconarticles" in schema:

{
  "kind": "collectionType",
  "collectionName": "lexiconarticles",
  "info": {
    "singularName": "lexiconarticle",
    "pluralName": "lexiconarticles",
    "displayName": "Lexiconarticle",
    "description": ""
  },
  "options": {
    "draftAndPublish": true
  },
  "pluginOptions": {},
  "attributes": {
    "name_de": {
      "type": "string",
      "required": true,
      "unique": false
    },
    "name_en": {
      "type": "string",
      "unique": false
    },
    "firstname": {
      "type": "string"
    },
    [...]
    "related_lexiconarticles": {
      "type": "relation",
      "relation": "oneToMany",
      "target": "api::lexiconarticle.lexiconarticle"
    },
    "products": {
      "type": "relation",
      "relation": "manyToMany",
      "target": "api::product.product",
      "inversedBy": "lexiconarticles"
    },
  }
}

Relations to other collection types also working.

Hey there @pointout @hsnbsst ! 👋

Thanks for reaching out and bringing up the issue you're facing. No worries, we're here to help you troubleshoot and optimize your Strapi project! 😎

To tackle the problem you're experiencing, let's start by cleaning up the cache. It's a good practice to delete the cache and .build folders in your project directory. By doing so, we ensure that any cached data or outdated build artifacts are cleared out. It's like giving your project a fresh start! 💨✨

In addition to cleaning the cache, it's also recommended to delete the node_modules directory. This step helps ensure that you have a clean slate for your project's dependencies. Once you've deleted node_modules, you can use either yarn install or npm install to reinstall the necessary packages. This process ensures that you have the latest and compatible dependencies for your project. It's like tidying up your project's shelves! 🧹📦

After clearing the cache and reinstalling the dependencies, give your project another try. Check if the issue still persists. If it does, please let us know, and we'll be more than happy to dive deeper and assist you in resolving the problem. We're here to help you get your Strapi project running smoothly! 🏃‍♂️🔧

Thanks for reaching out and helping us make Strapi "Strap-tacular"! 👍🥳

That way we ruled out any caching issues.

I deleted .cache, build and node_modules folder. Installed and built strapi new and started in dev mode and opend the admin in a private browser window. The error remains.

Hi there,
Issue still present after clearing the cache

[danieltorres1109]

I have the same problem.
Node.js version: Node 18.13.0
Strapi Version: 4.11.4

If you are as urgent as me, go from version "4.11.4" to "4.11.3".

change:
"@strapi/strapi": "4.11.3",
"@strapi/plugin-users-permissions": "4.11.3",
"@strapi/plugin-i18n": "4.11.3",

rm -rf node_modules

rm yarn.lock

yarn install

It's work for me
