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, Processor Intel Core i7-4930K@3.4GZ. 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.

If this previously worked with the same Blender version and now stopped working, it seems likely that there has been an automatic update that to your OS or graphics driver that you're not aware of which introduced the problem.

Blender checks for OpenGL support at startup. If this fails it usually is either an issue with the graphics driver, the OS or the hardware, should the GPU should provide a supported OpenGL version. Your hardware is supported and should work.

Please open Blender's installation directory and double click on the blender_debug_gpu.cmd. This will start Blender in debug mode and create log files. Try to make Blender throw the error again, in particular when you're able to open it properly and it throws an error later on. Once it does, close Blender. The Windows Explorer should open and show you up to two files, a debug log and the system information. Add them to your bug report by clicking on the upload button as shown in the screenshot below or via drag and drop.

Hi Robert. I have been unable to duplicate the error. I did verify that no drivers had been update. I have been unable to verify the source of the originating error. Power isolation and battery are fine. I can only speculate that unknown power event happened. Sorry to have wasted your time. Please close the ticket. Thanks.

Hello.

I have the same problem. I have Open GL 4.6 but while I work on Blender, Blender 3.2.1. version says I don't have Open GL 3.3 or higher version. What should I do?

"Please open Blender's installation directory and double click on the blender_debug_gpu.cmd. " Where can I find this file from?

@Muhammed-Baykul You can find the file in the installation directory of Blender, where the blender.exe is located. If you are using Windows and used the .msi installer, then it should be in C:\Program Files\Blender Foundation.

Please create a separate bug report for your issue though.
