Welcome to the Microsoft Community.
Thank you for your feedback. I carefully read the information and problem description you provided. You mentioned that you cannot open a file of a particular format and the error is: "File system error -2018374635".
Method 1. Run SFC and DISM commands to repair system files
Press Win + X or right-click the "Start" button and select "Command Prompt (Admin)" or "Windows PowerShell (Admin)".
Type and run the SFC command:
sfc /scannow
This command will scan all protected system files and replace damaged files. This process may take some time, so please be patient.
DISM can repair problems in Windows image files and is the next step when SFC cannot repair files.
Continue to use the command prompt with administrator privileges. Enter and run the following commands:
DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth
These commands will check and fix problems in the Windows image file. /RestoreHealth You may need to connect to the Internet to download and replace corrupted files.
Method 2. Update or reinstall the problematic application
Make sure Windows 10 and all applications are up to date:
Open the Microsoft Store, click the three-dot menu in the upper right corner, and select "Downloads and updates".
Click "Get updates" to make sure all applications and Windows system are up to date.
If a specific application is causing problems, try reinstalling the application:

Find and click the problematic application and select "Uninstall".
After uninstalling, reinstall the application through the Microsoft Store or the official website of the application.
Method 3. Repair all Windows applications via Powershell
Press Windows key + R to open Run and type: powershell

Method 4. If you have tried the above methods and the problem persists, create a new local account and test whether the problem persists.
Press Win + S to open the search bar.
Type cmd, then right-click Command Prompt and select Run as Administrator.
Type the following command in the command prompt and press Enter:
