I'm using HiGHS solver version 1.9.0 on Windows 11 on CMD terminal, using directly highs.exe executable, and in some cases (not always), the solution process hangs and never finishes completely as shown in the attached image.
I'm calling the solver using the command: highs.exe problem.lp
Does anyone know how can I solve this problem? Thank you

Reset to default 0This is a known issue. It seemed to be solved with a previous release, but apparently it was not completely solved. See the Github issues here for more information and updates: https://github/ERGO-Code/HiGHS/issues/2146 and https://github/ERGO-Code/HiGHS/issues/1670
One thing you can try is to set the number of threads to one.
