Prusa 2.6 Alpha 3 Not Able to Restart After Program closes - Open GL error - unable to switch to MESA OpenGL Library

[BJONES673]

Description of the bug

Whenever the Prusa program closes or crashes and I try to restart it, I receive an error "PrusaSlicer was unable to automatically switch to MESA OpenGL library". If I restart the entire computer, it will start, but even if the screen saver comes on, this error will appear. I have tried the "-- sw renderer" and that did not work. I tried to set the windows Mainframe to 0, 0 (window_mainframe = 0; 0; 2576; 1056; 1) and that did not work. I have two monitors and tried disconnecting the 2nd monitor and that did not work. I have tried to assign it to either the intel graphics or the Nvidia garphics card in my laptop (running Windows 10), no options worked there.
