How to disable out-of-process mode in ReSharper?

Answer

As of ReSharper 2025.2 EAP 6 release, the Out-of-Process mode is enabled by default.

To disable it, switch back to In-process mode by going to ReSharper’s Options | Environment | Products & Features and deselecting the Run ReSharper in separate process option.
