I am trying to run a program in a pre-existing Steam-created Proton prefix, as the program I am trying to run relies on the runtime package installed with RPG Maker 2003 (there are other ways to get the RTP but I don't want a duplicate and I'd have to do a similar step to install the RTP under a separate prefix). As can be seen in the Konsole screenshot, the file "proton" cannot be found. However, I have copied the path to this file directly from the Thunar window (in the second screenshot) where the file can be seen. What gives?
