Release notes
[1.52.99] - 2026-07-11
Fixed
- The Gaming Profile crash-recovery sweep reverted the leftover session and rewrote its store without holding the service lock, so a quick Start click could race it. On launch, if a previous run closed with game-mode tweaks still applied, the tab offers to revert them via RecoverPendingAsync. Unlike ApplyAsync and RevertAsync — which both serialize on the service's SemaphoreSlim (_gate) — RecoverPendingAsync ran its RunRevertAsync and its LoadStore→SaveStore completely ungated. After the user answered the "restore?" dialog the UI was live again, so clicking Start launched ApplyAsync concurrently with the still-running recovery revert: two paths reverting/applying the same machine-wide tweaks (power plan, visual effects, search indexing, notifications) and doing an unsynchronized read-modify-write of the on-disk store — which could lose the ActiveSession = null clear (resurrecting the leftover marker so it re-prompts forever) or interleave conflicting tweak steps. RecoverPendingAsync now acquires _gate for its whole body (mirroring RevertAsync, including the ConfigureAwait(false) that keeps the gate-release continuation off the UI thread so Dispose's shutdown _gate.Wait() can't deadlock) and re-reads the store inside the gate so the read-modify-write is atomic against a concurrent SaveStore.
