Can't use Regex from System.Text.RegularExpressions with UE 5 in Build.CS

[_h2o]

Just to keep tracking of issue - i have found same topics with UE 5.0 EA, so issue is stil there. Provided solution is not a solution using binary build

UE4 C++ Migration to UE5 - Issue with a Plugin Build CS File... (Regex)

Just a quick heads up and a big thanks: Your solution worked like a charm. I did have to ensure that the project of UBT is rebuilt by cleaning and building it manually. Once that was done I was able to generate the project files just fine!

Fix is comming in 5.1
