Big Sur update on iMac M1 will not install

The update to Big Sur going from Big Sur 11.7.5 to Big Sur 11.7.6 will not download on my iMac M1. The update bar just keeps checking for update. I've tried many times, and even let this 'checking for update' run all night. Any suggestions? I don't want to upgrade to Ventura...I have that on my MacBook Pro Max M2.

FWIW, if that doesn't work, you may have to download the full 11.7.5 installer. Run this command in the Terminal…

softwareupdate --fetch-full-installer --full-installer-version 11.7.5
