Latest version of Unity 6 (29f1) does not work even when no LTO option is selected. The build crashes on any WasmCodeOptimization except for BuildTimes.

Resolution Note:
Thank you for bringing this issue to our attention and for taking the time to report it.
Following a thorough review of the reported problem, we have determined that the root cause lies within the Emscripten codebase. While we anticipate that this issue will be addressed in a future Emscripten update, we recommend avoiding the use of the LTO build option as a temporary workaround.
At this time, we will be closing this case. However, we encourage you to monitor upcoming Emscripten releases for relevant updates and improvements.
Thank you again for your valuable feedback and for helping us improve.
