Thanks for the backtrace!

The problem is most likely that your C:\xampp\apache\bin\MSVCP140.dll is a bit old. It's 14.34, while our ICU builds used 14.41, whereas the builds from ICU used 14.38. Apparently, somewhere between 14.38 and 14.41 an incompatibility was introduced. To verify, I found an older msvcp140.dll (14.26), put that early in the search path, and got the same crash.

I suggest you download the latest Microsoft Visual C++ redistributable (direct donwload link), and install it. Then rename the old C:\xampp\apache\bin\MSVCP140.dll (or delete it, but consider to keep a backup, just in case), and see whether everything is fine. If not, open a cmd.exe in C:\xampp\apache\bin, and run where msvcp140.dll to see which msvcp140.dll is used, and replace if necessary.

And possibly you don't even need to install the latest Microsoft Visual C++ redistributable; you may already have a recent version installed. Maybe just rename C:\xampp\apache\bin\MSVCP140.dll, and see what happens.

Anyhow, welcome to DLL hell!
