when i click file explorer from task bar it crashes and didn`t start

First determine whether Explorer crashes specifically when opening, previewing, or browsing DWG files, because Autodesk documents an AutoCAD-related Explorer crash for DWG opening; otherwise, isolate the AutoCAD installation’s background integration with a clean boot before repairing Windows.

1. Check whether this matches Autodesk’s documented issue

AutoCAD 2027 supports 64-bit Windows 11, so installing it on Windows 11 is not itself an unsupported configuration.^1^

Test these separately:

1. Open This PC and leave it open without selecting files.
2. Browse a folder containing no DWG files.
3. Browse a folder containing DWG files, but do not select one.
4. Select a DWG file or enable its preview.
5. Double-click a DWG file.

If the crash occurs only when selecting, previewing, or double-clicking DWG files, use Autodesk’s product-specific article and apply its current workaround.^2^ Avoid browsing DWG folders in Explorer until the workaround is applied; open drawings from inside AutoCAD instead.

Do not use Autodesk’s separate launch-crash procedure unless AutoCAD itself displays the documented Program Error while starting.^3^

2. Identify the crashing component

1. Press Win+R, enter eventvwr.msc, and press Enter.
2. Go to Windows Logs → Application.
3. Find an Error recorded at the exact time Explorer crashed.
4. Open it and record:
   • Faulting application name
   • Faulting module name
   • Exception code
5. If the module belongs to Autodesk or an AutoCAD Explorer component, use the Autodesk workaround or contact Autodesk support with those details. Do not delete DLL files manually.

Explorer errors at the crash time can identify whether explorer.exe, a shell component, or third-party code is failing.^4^

3. Test for an AutoCAD-related background conflict

A clean boot temporarily starts Windows without non-Microsoft services and startup applications. It does not reset Windows, but some features may be unavailable during the test. Administrator access is required.

1. Press Win+R, enter msconfig, and press Enter.
2. Open Services.
3. Select Hide all Microsoft services—this is essential.
4. Select Disable all, then Apply.
5. Open Startup → Open Task Manager.
6. Disable enabled startup items, noting their original state.
7. Restart and test File Explorer for longer than five minutes.

If Explorer stops crashing, re-enable half the disabled services and startup items at a time, restarting after each change, until the responsible item is isolated. Microsoft documents this half-at-a-time isolation procedure.^5^

After testing, open msconfig, select General → Normal startup, and restart. If an Autodesk item is isolated, leave only that item disabled temporarily and obtain an update or correction from Autodesk.

4. Repair Windows components

If Explorer still crashes during a clean boot, open Terminal (Admin) or Command Prompt (Admin) and run DISM first, followed by SFC:

DISM.exe /Online /Cleanup-Image /RestoreHealth
sfc /scannow

Wait for each command to finish; do not close the window before SFC reaches 100%. Restart and retest Explorer. DISM repairs the Windows component source, while SFC checks and replaces protected system files.^6^

5. Nondestructive recovery fallbacks

Before either option, make a separate copy of the active project. Personal-file preservation is not a substitute for a backup.

System Restore: Since the problem began during the AutoCAD installation, press Win+R, run rstrui.exe, and choose a restore point immediately before that installation. Select Scan for affected programs first. System Restore preserves personal files but rolls back system settings, drivers, and installed applications changed after the restore point.^7^

Repair-reinstall Windows: If no usable restore point exists, go to Settings → System → Recovery → Fix problems using Windows Update → Reinstall now. This reinstalls the current Windows version while preserving files, applications, and settings.^8^

That option requires Windows 11 22H2 or later and the February 2024 optional update or a later update. It can also be unavailable on work-managed devices. In that case, contact the organization’s IT administrator rather than resetting the PC.
