Additional context

Link to the log

Currently I do not support PolyMC at all. Try MultiMC and see if it works for you.

A PolyMC dev confirmed that this is a PolyMC bug.

As a temporary fix, go to the instance's settings, then custom commands, and replace "$INST_JAVA" with the path to Java's binary. You can find the one the instance uses in the "Java" tab, also in the instance's settings.
