You didn't mention if the A10 is a laptop or Desktop APU processor. Either way the A10 Integrated Graphics is a legacy APU.
I don't know about your GPU Cards but if they both are Non-RX GPU cards then they are considered to be Legacy also.
Thus depending on what AMD GPU models your have and A10 APU Processors, the last AMD Support AMD driver is from 06/2021 or older is for Windows 10 only. There are no Windows 11 drivers nor will there be any in the future.
So if the Windows 10 AMD Drivers doesn't work in Windows 11 correctly there is not much you can do except eliminate any problems that could be causing your issues and effecting the AMD Graphics driver.
If the main issue is if the AMD Graphics Drivers isn't 100% compatible with Windows 11 then there is not much you can do.
Now if you have Windows 10 installed and Overwatch is the only game being affected that pretty much indicates it is either the AMD Driver (legacy) for the A10 and if you have Non-RX GPU Cards installed is probably too out-dated for that game.
If you have RX GPU cards with the latest AMD Graphics driver than I would check Overwatch developers for any recent game patches or wait until the next AMD driver comes out to see if it fixes your issue.
Either way I would report it to AMD Support for the computers with GPU cards and they are RX GPU cards to AMD from here: https://www.amd.com/en/support/contact-email-form
