Follow these steps:

1. Download the free version of Revo uninstaller and uninstalled nitro sense with it. It's important to let revo scan after uninstall because it'll find garbage files in registry that sense leaves behind and probably corrupts any new install. Let it clear those files.
2. Go to Acer's website and download Nitrosense for your laptop. (If there's different version of nitrosense available then try them all one by one and check which one work for you)
3. Extract folder and run Setup.exe
4. Run Command prompt as Administrator
5. type in the following and press enter (without the quotation marks): ".\lodctr.exe /R"
6. Go back to the folder where you extracted Nitrosense
7. Go into "Nitrosense V3.1" folder
8. Run APPXBUNDLE file
9. After that, Nitrosense immediately launched, and now it's back on my Taskbar, running every time I click on it.

If issue, persists:

Then download and install the Microsoft Visual C++ All-in-One pack. Since NitroSense requires specific versions that may not be available on your laptop, this will help. Use the link I provided to download and install the latest Visual C++ All-in-One pack. Make sure to install both the x86 (32-bit) and x64 (64-bit) versions one by one to ensure full compatibility. As applications require both versions, even on 64-bit systems, because some programs are built for 32-bit and others for 64-bit environments

Download all in one lack from below link and run:

2. Reset WMI service. Open CMD as administrator then run below command and restart your laptop.

winmgmt /resetrepository

Scan for hardware changes

This is the fastest method to try, as it forces Windows to redetect the devices.

1. Right-click the Start menu and select Device Manager.
2. In the Device Manager window, click the Action menu and select Scan for hardware changes.
3. Check if your Bluetooth and camera devices reappear. If they do, restart your laptop. 

Temporarily roll back the update

If the problem began immediately after the 25H2 update and none of the above solutions work, you can temporarily roll back the update.

1. Go to Settings > Windows Update.
2. Click Update history.
3. Select Uninstall updates.
4. Find the relevant 25H2 update (e.g., KB5051987) and click Uninstall.
5. Pause your Windows updates for 35 days to prevent the problematic update from reinstalling.
