Xcode 15 Beta 3- 6 .scn and .dae file crash

is any one else having issues with game scene-view .dae and or .scn files

it seems these new beta release is very incompatible with files that work perfect with previous Xcode releases up to Xcode 14 I'm working on upgrading a simple striped down version of my chess game and run in to strange and bogus errors messages and crashes

/Users/helmut/Desktop/schachGame8423/schach2023/scntool:1:1 failed to convert file with failure reason: *** -[__NSPlaceholderDictionary initWithObjects:forKeys:count:]: attempt to insert nil object from objects[0]

all tools reality converter exporting the .dae file to other graphic files working fine as in prior Xcode releases but some thing is missing in current beta release of Xcode 15

Xcode 15 Beta 3- 6 .scn and .dae file crash
