**System Information** Operating system: Windows 10 Pro version 20H2 OS Build 19042.685 w/ Windows Experience Pack 120.2212.5510 Computer ACPI x64 PC (EVGA 980X) w/ 16.0 GB RAM No pen or touch screen, Only MX Revolution Bluetooth Mouse and Keyboard Graphics card: 2 X NVIDEA GeForce GTX 780 using driver version 27.21.14.5671 from 2020-09-30 supporting Open GL 4.3. Each adapter has 2072 MB available **Blender Version** Broken: 2.91.0 Worked: until today. **Short description of error** When opening saved files the software reports Open GL 3.3 is not supported. The software would self shut down after. This is a stability issue. **Steps Taken** I am a new user (for the last 2 weeks) and this is the only version I've used. No updates have been installed on the computer since 2020-12-24. All files could be opened and edited prior to today (2020-12-30). The programs were used multiple times per day since the last updates were installed. Verified 100% support for all versions of OpenGL up to 4.6.0 NVIDEA 456.71 using driver GeForce Drivers 4561.719-30-2020 Version 80.10.3a.0.57, DirectX supported profile 11.0 and Shader model 5.0, and Vulcan version 1.2.142 by using OpenGL Extension Viewer 6.1.5.0. The DirectX Dignostic Tool (dxdiag) reports support for DirectX 12. Reinstalled graphics card drivers. Reinstalled Blender. Multiple reboots. Hardware reports 100% operability. Nothing affected the outcome. **Exact steps for others to reproduce the error** Currently I am only editing wire frames. Launch Blender from either a shortcut or start menu. Sometimes the program failed at launch before main screen started. Other times: 1) Select file from the opening face page. and the error is reported. 2) Select from the menu File->Open Was able to only access the files after a successful program launch and menu select Edit >Preferences->System. Under Cycles Render Devices separately clicked on None, CUDA, Optix, and OpenCL. Once leaving the menu, I could then open and edit a previously saved file during the current session. The system would stabilize for a period of time consisting of several uses before repeating the problem.
