Go to the support page for your laptop on the Acers website, then from there, download and install the version of Chipset drivers they recommend and while there, if you do not have your drive encrypted with Bitlocker, check for any BIOS update that may need to be installed

If that does not resolve the problem, then the best option to undo any damage that may have been caused by that update, is to perform an in-place repair with the Windows 11 ISO.
Please ensure you download the ISO in the same language as you use for the Windows UI, follow the steps, this is then not like re-installing Windows, it is just like an update and your personal files, settings and installed software will not be affected.

to download the Windows 11 ISO
When the ISO file completes downloading
Disconnect from the Internet
Disconnect all external devices with the exception of a mouse or keyboard.
Temporarily disable any 3rd party Anti-virus you may have installed
Then, in Windows File Explorer, double click the ISO and then run Setup.exe and select the Install option.
Very Important - ensure you select the option to keep your files and apps.
