I am seeing "MD5 hashing algorithm is no longer valid" errors when attempting to activate an updated extension on Sandbox.

{
  "type": "error.SuiteScriptError",
  "name": "55451",
  "message": "MD5 hashing algorithm is no longer valid",
  "stack": [
    "createError(N/error)"
  ],
  "cause": {
    "message": "MD5 hashing algorithm is no longer valid",
    "stack": [
      "createError(N/error)",
      "getMD5Hash(/SuiteBundles/Bundle 374045/ExtensionMechanism.Server/Services/FileApiSS2.js:338)",
      "reduce(/SuiteBundles/Bundle 374045/ExtensionMechanism.Server/CompilersMapReduce/JsCompilerMapReduce.js:336)"
    ],
    "name": "55451"
  },
  "id": "",
  "notifyOff": false,
  "userFacing": true
}

I've seen some similar errors above, but not exactly the same. Any insight? We have been facing a growing number of deployment and activation errors with setups that worked fine up until last week or so.

Update the extension manager

thank you for the quick response. Updated Extension manager and will try again.
