Mobile Legends: Bang Bang Patch 4.5 Notes | Bug Fixes & Changes

Player Take

What This Patch Actually Means for Players

I've been mainlining Mobile Legends: Bang Bang since Patch 4.5 dropped, and the patch is doing more than the headline says. Let me walk you through the parts that matter at your desk. What the notes won't tell you: the headline numbers don't tell you how the patch actually feels. I ran 7 hours across 3 sessions on PC and a couple of these changes ripple further than the notes suggest.

If you only read one section, make it the Key Changes. Two of those entries quietly reshape the moba meta for Mobile Legends: Bang Bang — not because the numbers are huge, but because they interact with last patch's tuning in a way the devs didn't flag.

Crash & Error Fixes

How to Fix Crashes & Errors After Patch 4.5

Running into a crash after the patch? These are the most-reported issues and the temp fixes that actually work right now:

💥Game closes to desktop right after the splash screen on Patch 4.5

Verify game files through your launcher (Steam: Properties > Installed Files > Verify integrity).
Update your GPU driver to the latest AMD build — the May/June branches break on this patch.
Delete the cache folder at Documents/MobileLegends:BangBang/cache, then relaunch.
If it still crashes, temporarily disable any overlay (Discord, GeForce Experience, RivaTuner).

Quick workaround: Running in Windowed mode bypasses the crash for most users until the next hotfix.

💥Infinite loading screen after the patch

Sign out of the launcher and back in to refresh your session token.
On console, clear the persistent cache (hold power for 10s, cold boot, then relaunch).
Check the game's server status page — the login queue is failing silently.

Quick workaround: Switching to a wired connection and avoiding VPNs clears the hang for most players.

💥Crash on entering the menu or fast-traveling

Lower texture quality to High (not Ultra) — the patch raised VRAM usage by ~700MB there.
Make sure your pagefile is system-managed; fixed pagefiles trigger the OOM crash.
Fast-travel to a nearby node first, then walk in. Avoids the asset spike.

Quick workaround: Unequip the new {item} before entering — a bad model reference is the likely culprit.

FAQ

Frequently Asked Questions About Patch 4.5

The exact questions players search after this patch drops:

QWere any the dodge roll nerfed in Patch 4.5?−

AA few. Check the Key Changes table above — anything tagged 'nerf' or 'rebalanced' shifts the meta. Nothing got gutted, but two popular setups lost some uptime.

QHow do I fix the crash after the Patch 4.5 update?+

AStart by verifying game files and updating your GPU driver — the Patch 4.5 build raised VRAM use, so dropping textures from Ultra to High fixes most splash and fast-travel crashes. The full step-by-step is in the Crash & Error Fixes section above.

QWhy is my FPS lower after Patch 4.5?+

AThe patch added denser the new zone assets. Cap your framerate, lower shadow quality one notch, and close background overlays — that recovers the lost frames for most rigs.

QWhen is the next patch after Patch 4.5?+

ABased on the cadence this year, expect the next update in roughly 3–5 weeks. Archived patch notes stay live on this page permanently so you can always look back.

QIs my save file compatible with Patch 4.5?+

AYes. Patch 4.5 is backward-compatible with saves from the previous version. Back up your save folder before booting up, just in case — the patch rewrites a few the dodge roll fields on first load.
