@NaikoReQlo The directory you installed the game into is not whitelisted in Heroic's permissions. When you selected it on install, you gave Heroic one-time permissions to read/write to it, but those got revoked once you closed Heroic again. Use Flatseal to give Heroic permissions to write to the directory, then select "Move Game" in the 3-dot menu on the game page & select the proper path
