Just chiming in to add I found the same problem after updating to the newest version. Runtime: v2023.2.0.87. Using gmlive-server-alt works for scripts, gmlive-server does not. Running gmlive-server in admin didn't make a difference. Noticed there's a small difference between the two when starting the game. Start up log below:
GMServer: ready! 1 live file, 0 global vars, 192 macros, 0 scripts, 49 enums. Took 2923ms.
GMServerAlt: ready! 2 live files, 0 global vars, 192 macros, 0 scripts, 49 enums. Took 972ms.
I didn't see any error messages in the output log.
