Issues with waking the laptop from sleep

Hello, I have the DIY Edition (13.5", 1135G7) and have installed Windows 10 on it. It has some issues with waking up from sleep mode sometimes, especially when I plug it in to my Thunderbolt dock. When this happens, the led light around the power button flashes and I am unable to turn on the screen. I did update the BIOS to the latest version as of December 2021 and installed the driver bundle from December as well. Any idea what the issue could be? Thanks for your help.
