QB Desktop 2016 doesn't support Win 11 natively. There may be an update in Win 11 that is conflicting with your QB Desktop 2016.
You may consider the following steps
1. Install the trial version of QB Desktop 2016 Enterprise to open your file and export the template file for memorized reports.
2. Install the trial version of QB Desktop 2019 Pro to open your file and import the memorized report template files.
If it works, you may consider to use a newer QB Desktop with non subscription license to proceed. Contact me in private and we will share the installer file.
