Start with the linked baseline commit ca073c0866e1504313b43781c209f7f680d0ecb3 and compare commit 975877333c98d9d08bad66670d74accc6047be34, then inspect the SOD - Android HelloWorld Extracted Size reports for the arm64 Windows configuration. Confirm which change accounts for the reported size regressions and verify the performance report no longer shows them.
