## Bug fixes

### [Hot Fix] Expression Tree Errors (CS9226 & CS8640)

Fixed compilation errors that occurred when .NET 9 or later was installed on the system. The errors `CS9226` and `CS8640` were caused by params span overloads introduced in .NET 9, which conflicted with expression tree usage in the CLI.
This issue was resolved by updating the `rollForward` property in `global.json` from `latestFeature` to `latestMinor`, ensuring the CLI uses only .NET 8 features.

:::note
UiPath CLI 25.10.5 is designed to run on .NET 8. While .NET 9 can be installed on your system, ensure that the CLI uses .NET 8 SDK to avoid compatibility issues.
