Try reinstalling and running your QBD 2011 in compatibility mode Win 7 on your Win 10. Half of our team is still running QBD 2011 and 2012 on Win 10 Home 20H2 to date. We don't dare to upgrade our Win 10 version and we were still using 1909 this year until Windows forced us to upgrade the version 8)

It it didn't work with you, consider upgrading your data to QBD 2020 or 2021 with a one time license. Contact us in private for assistance.
