VS 2026 crashing on Save with ReSharper enabled.
I created a support ticket for this (8887611) issue and got a confirmation email but when I click on the link to the support ticket I get a 404 not found? Anyway ….
Doesn't matter what mode I run ReSharper in Out-of-Process or In-Process it will frequently cause VS to go unresponsive as soon as I click on the “Save All" button in the VS toolbar. This is ONLY started happening with the ReSharper version 2026.x.x. I've tried all the recommended solutions except #4 source control (pointless to proceed without source control) and NONE have solved the issue:
Recommended Fixes
Try these steps in order to stabilize your environment:
-
Clear ReSharper Caches: Corrupted caches often trigger exceptions during auto-save or background compilation.
- Go to Extensions > ReSharper > Options > Environment > General.
- Click Clear caches. Restart Visual Studio.
-
Disable Out-of-Process Mode (if active): If you are using ReSharper’s new out-of-process engine, it may be unstable on certain configurations.
- Go to Extensions > ReSharper > Options > Environment > Products & Features.
- Uncheck Run ReSharper in a separate process and click Apply to run in-process
-
Toggle Solution-Wide Analysis: Constant background analysis on save can overwhelm system memory.
- Go to Extensions > ReSharper > Options > Code Inspection > Settings.
- Uncheck Enable solution-wide analysis temporarily to see if the crashes stop.
-
Disable Visual Studio Git/Source Control Integration: Source control plugins trying to lock files immediately upon a ReSharper-assisted save can cause a hard crash.
- Go to Tools > Options > Source Control > Plug-in Selection and set it to None.
-
Exclude Folders From Antivirus: Windows Defender or other antivirus software actively scanning changing cache directories during a save operation can lock files and force Visual Studio to crash.
- Add the ReSharper cache folder (
%LOCALAPPDATA%\JetBrains\Transient) and your project directory to your antivirus ignore list.
- Add the ReSharper cache folder (
I've also tried the standard other options:
Visual Studio 2026 repair
OS - sfc /scannow and DISM options
The ONLY option that prevents VS crashing is if I disable ReSharper. I can't continue working like this so I need a solution, if I can't get one then I'll stop using ReSharper and cancel my subscription … not trying to be dramatic just a fact as I got a million other tasks on my plate and debugging ReSharper isn't one of them.

Hi, thank you for your time and feedback!
I see a lot of exceptions from Telerik.Blazor.VSPackage.BlazorCompletionCommandHandler in your logs, but they are probably not related to the hang. Unfortunately, the logs do not make it clear why this happened.
Could you please collect a PerfView snapshot as described here: https://youtrack.jetbrains.com/articles/SUPPORT-A-2191 (use the PerfView_until_S_pressed.cmd script).
Thanks
