unable to play since latest season update

Hi, sorry to hear you're running into this.

Please check the steps below:

• Make sure your drivers are fully updated and installed correctly. You can also try rolling them back to see if that makes a difference. It’s extremely important to perform a clean driver reinstall using a tool such as DDU, as a standard reinstall often does not fully resolve driver-related issues.
• Make sure your Windows version is fully updated.
• Make sure you are not undervolting your GPU or modifying the graphics card clock speeds.

Once the above is completed, you can try some of these workarounds found by the community for now:
- Add the launch option -no_render_on_input_thread to your game's settings.
- Remove Realtek drivers and let Windows install generic ones. Check here.
- If you're using a sound card, make sure its drivers are updated (or disconnect it to check if it does something). Example here.
- Disable virtualization and X3D Gaming Boost (or Intel Game Boost) in your BIOS, and set up power save mode.
- Downgrading your motherboard BIOS to a previous version.

Let me know how it goes.

If none of the steps help, do you see any related errors in Event Viewer? You can also attach your DxDiag report to help with troubleshooting.
