Can't compile

Step 2/4. Running benchmark for pgo-build ...
./stockfish.exe bench > PGOBENCH.out 2>&1
make: *** [Makefile:948: profile-build] Error 1

The error is mine or global?
Thanks

I tried but it failed again, same message.
Today I had an MSYS2 update. And yesterday I updated Windows 24H2.
The only differences since my last compilation is commit "Increase PCM bonus when cutOffCnt is low".
