1x GSE\API\Events.lua:116: attempt to call field 'PrintDebugMessage' (a nil value)

Possible Fix:

Change version number in all 3 TOC files from
## Version: 2.6.01_SL_alpha8
to
## Version: 2.6.1

This fixes the error in Retail and Shadowlands beta! Confirmed and tested by myself (Retail) and Lutechi (Beta).

Fixed in https://github.com/TimothyLuke/GnomeSequencer-Enhanced/releases/tag/2.6.01-alpha9-shadowlands
