I have moved your post to its own dedicated topic to attract wider attention to it. In the meantime, please help others to help you by providing an better description of your issue using many more words.
In this case, the following command might help; let the command finish completely (in might take a minute):
pamac upgrade -a --force-refresh --dry-run
and then if that completes without error:
pamac upgrade -a --force-refresh
After successful completion you might try again to build the package:
pamac build intel-ivsc-firmware
I hope this helps.
PS: Feel free to change the thread title, if needed.
Regards.
