VMM freezes on Install Modes stuck

Wondering if anyone in the community could please help. Using crt emu 2.0 beta 15 18.5 with a R5340 I repeatedly get stalled after hitting install modes. It goes to modelist install, installing modelines in system, 120 mode lines installed. THEN after a flicker on screen it just stops there. I’ve tried removing drivers and repeating the process to no avail. Any help would be greatly appreciated. TIA
