Why does the built-in wifi adapter not see some networks?

On an acer laptop, windows 10 was updated for a long time, the user turned off the power by about 30%.
The laptop turned on the next day. But the wifi adapter stopped seeing the desired wifi network, it only sees the wifi point on the printer. It connects well to it. I did not create other access points. If you use an external wifii adapter, then it sees the desired network and connects to it. I tried resetting the network through windows settings - it did not help. Recovery points are not rolled back, writes a failure during recovery, rollback is not performed. Deleted adapter drivers - didn't help. Restarting the wifi router didn't help. Wifi worked fine before the update.
What else can be done in this situation?
Thanks in advance.

There was a similar problem on windows 7 The
built-in wi-f adapter of the laptop selectively saw networks.
It helped to update the drivers to a newer version with a restart of the laptop.
Maybe try uninstalling the drivers, reboot.
Determine the adapter model and download newer ones from the adapter manufacturer's website.

Have you tried manually creating a connection?
You can see the networks here and delete the extra ones:
Create a batch file with the following content, run as administrator and enable "Hidden" in the launched Device Manager:

set devmgr_show_nonpresent_devices=1
start devmgmt.msc
