Error message

There are already some resources being updated while playing.

What it means

ApplyResources throws this when there are pending while-playing resource updates (m_UpdateWaitingInfoWhilePlaying non-empty). Queued resource downloads that trigger during gameplay would conflict with applying a resource pack, so the manager rejects the call.

Solutions

1. Wait until all while-playing updates finish (no pending download requests) before applying the pack
2. Apply resource packs before starting gameplay/scene loads that enqueue while-playing updates
3. Check the ResourceManager update state / pending counts before calling ApplyResources

Example fix

// before
LoadScene("Battle");           // queues while-playing updates
resourceManager.ApplyResources(packPath); // throws
// after
resourceManager.ApplyResources(packPath); // apply first
// then load scenes once apply-success callback fires
LoadScene("Battle");

// ensure no while-playing updates are pending before applying
if (m_PendingWhilePlayingUpdates) return;

try { resourceManager.ApplyResources(packPath); } catch (GameFrameworkException ex) { Log.Warn("While-playing updates pending: " + ex.Message); }

When it happens

Trigger: Calling ApplyResources while resources are queued for download during play (e.g. a scene load requested assets that entered the while-playing update queue); applying a pack immediately after triggering scene loads.

Common situations: Hot-update flows that both download missing resources during play and apply a local pack; loading a scene on startup before applying the pack that contains its resources.
