    here is the blob from defender.

    There were problems installing some updates, but we'll try again later. If you keep seeing this and want to search the web or contact support for information, this may help:• Definition Update for Windows Defender - KB2267602 (Definition 1.239.586.0) - Error 0x80070643

    Win10 Version 21H2 19044.1645

    A computer restart after the notice solved the issue for me.
