We are having the exact same issue in multiple companies so it's not the database but the software updates.  Running Windows 2012R2 as well.  I did various diagnostics and rebuilds to no avail and the rebuild errors and reports won't open.  We are also using QBE 23 Contractor and Accountant.  I've reran the updates and installs.  The problems started with the V33.0D R12 05/07/24 update.
