Swift 3 fingerprint reader stopped working

Yesterday my Swift 3 fingerprint reader stopped working. I use Windows 11. When I go into the Device Manager, and go to Biometric Devices/EgisTec Touch Fingerprint Sensor, I get the following under Device Status:

“This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)

Insufficient system resources exist to complete the API.”

Some background: A couple of months ago I updated to Windows 11, and the fingerprint reader stopped working. So I uninstalled 11 and web back to 10 and it worked again. A few days later I reinstalled 11, and the fingerprint reader worked fine, and it has worked fine since then until yesterday. Thanks for any help.

Sometimes a simple system restore will fix the issue..

Try windows x
click on power shell admin or command prompt admin
type rstrui
chose an earlier date on which your computer was working fine
click on next, finish, yes
It will restore your computer to an earlier date
if you get an message - system restore not completed - click on close
It will show you all the icons..

Try and check whether it is working now ..

If it is still not working ..

Tried windows x
click on device manager
Uninstall the finger print reader
Restart the computer

It should work fine ..

If it is still not working
Go to support.acer.com
chose your country
type snid or chose your model
go to drivers - Install the finger print reader..

I have a similar problem. I was following this guide, the most promising is uninstalling the device and then restarting, however it seems to one work for about a day or less, then the issue appears again.
How To Fix Code 31: This Device Is Not Working Properly (minitool.com)

Now, the SNID of the computer is 02400439334, and model is SF314-42-R6T7.
If I click to update driver (in Device Manager), it shows I am on the latest update:

I believe this message is accurate, I checked Acer's website for any newer drivers for the sensor:
Product Support | Acer Indonesia

There is no Windows 11 operating system in the drop-down.

But I noticed that Product Support for model SF314-43 does have support for Windows 11.
Now, my question is:
1. Is there a driver in development for SF314-42? and if not..
2. Is it fine to download the newer EGISTEC fingerprint scanner driver from the SF314-43 page?

Thank you for your help. It is much appreciated as I have been dealing with this issue for some time.

This is a follow-up to my previous comment. I decided to go through with downloading the driver from the SF314-43 page. And I chose the option Browse my computer for drivers and selected the driver folder.

So far, it seems to work. I will add another comment if it breaks again. I am assuming the driver is written by EGISTEC for the Windows 11 OS.

Thanks for the responses. Several hours after I posted this, the fingerprint sensor started working again, without me having done anything to address it. Not even rebooting (which I had previously tried a couple of times). So I don't know what changed, but happy to have it working again.

Another follow up, my fingerprint reader wasn't working this morning. I wonder if this is happening when I haven't rebooted in a semi-long time? After I rebooted, the fingerprint reader did work.

I'm experiencing a similar issue. On the support web site found a second driver option (different vendor). Anyone tried this Elantech driver?

You should look at which sensor is installed on your system in Device Manager under Biometric devices. My system is using an Elan sensor, so the second download would be correct for me.

Same issue is now affecting my laptop. Disabling and re enabling the sensor is device manager works as a short time fix but then the problem returns.

I have tried all above steps. Any help with this? @Acer-Blayn @Acer-Brad or anyone else?
