Anytime I add a landscape to a level, then building and launching on the quest 2, It keeps crashing while giving this error. Other forum posts talked about materials being the issue, or deleting the binary and intermediate folders helping, I tried these things but the issue persisted. This only started today; yesterday the project ran smoothly.

I would like to add that this only happens when there’s a landscape in the level. This isn’t happening without the landscape.

I’d appreciate it if someone could help, and maybe even explain how to understand the error log better.
Thank you

any luck? Just ran into the same thing, indeed, when adding a landscape and trying to build to the Quest.
