Stormblind Complex crashes on startup after game re-install - iMac - Mojave

[IllKIllU3]

HI,
Recently I had to re-install BL3 on my iMac 27, 2019, Mojave.

Since then, the Map Stormblind Complex doesn’t start.

The Map hangs on the loading screen. If I take a look at the Activity Monitor app I see that the game starts to eat Compressed Memory like crazy. Until it reaches 200gb!(see attachment). Then the game crashes and have to force quit it.

This only happens on this map since the re-install.

I verified game files, re-installed the full game and addons (all 240 gb!) several times and even tried a time machine restore, to no avail.

Any help is appreciated!
Thanks,
A.
