Thanks to Mclane for working with me to identify the problem with running Colossus in Arena.
Unfortunately I've introduced a new bug in the multi-threading code so it will sometimes crash if you set threads > 1
Single threading works fine.
The good news is that I know what the bug is so it will be fixed in the next version, hopefully early in 2025.
Colossus 2024a now available

Thanks again!
Have one more look at Syzygy- usage in Arena (and Shredder) too, I didn't have any problems with threads >1 as long as Syzygy- path wasn't set, editing this one UCI- parameter made engine freeze in Arena (3.5.1) and Shredder (13), even if path was set in .ini- file too. No problem in console, just in GUI.
Edit: hadn't read your PM before writing this, no spaces in my Syzygy- path:
