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.
