The error you’re encountering in UiPath Studio, stating “Studio closed the active project due to a critical internal error”, is typically caused by corrupted project files, invalid dependencies, or version mismatches.
To resolve this, first delete the .local folder, project.settings.json, and project.json.lock file from your project directory. Then, try reopening the project via “Open from Folder” in Studio, preferably running Studio as administrator. If it still fails, open a blank project and import .xaml files one by one to identify the corrupted file.
Also, ensure all packages are updated to stable versions using the Manage Packages panel. If needed, downgrade to a stable UiPath version like 2022.10.x. Reviewing detailed logs under %localappdata%\UiPath\Logs can also help pinpoint the issue.

Could you please try reinstalling .Net runtime?
Also could you please confirm what’s the processer (CPU) of your machine? There could be possible limitation of specific CPU like Snapdragon or AMD.
At the time of install UiPath studio (version: 2025.0.167 STS) few months ago it has asked me to install windowsdesktop-runtime-6.0.36-win-x64 but after UiPath studio update (version: 2025.0.172 STS) it has by default installed .net runtime (version : 8.0.15) at location : C:\Users\user\AppData\Local\Programs\UiPath\Studio\shared\Microsoft.NETCore.App\8.0.15
What I have to do while reinstalling .Net runtime? Please give me steps to resolve .net runtime issue
Note :- I have installed .Net Runtime windowsdesktop-runtime-6.0.36-win-x64.exe and currently there is no specific .net runtime (8.0.15) exe I have installed in system
