If the game refuses to start, first check the integrity of files through GOG Galaxy or Steam — go to the game properties and run a file verification. Corrupted or missing files are the most common culprit. Also make sure your GPU drivers are up to date; NVIDIA and AMD release patches specifically tied to major Cyberpunk 2077 updates.
Sudden crashes without an error message usually point to RAM instability or overheating. Run a temperature monitor like HWiNFO64 while playing and check if your CPU or GPU hits critical thresholds. If temps are fine, try disabling XMP/EXPO profile in BIOS — aggressive memory overclocking often causes random crashes in this game specifically.
If cloud saves stop working in GOG or Steam, check whether the sync feature is enabled in the client settings. Sometimes the client loses connection silently and saves only locally. Manually back up your saves from Documents\CD Projekt Red\Cyberpunk 2077\saves just in case.
After any patch, mods — especially Cyber Engine Tweaks and Redscript — need updated versions. Check Nexus Mods for compatibility notes before launching. If the game crashes on startup after an update, disable all mods first by removing the 'bin\x64\plugins' folder temporarily to isolate the issue.
This usually happens with Bluetooth headsets or certain USB DACs. Switch audio output to a standard wired connection and set the in-game audio device explicitly rather than leaving it on 'Default'. Also check that your Windows audio sample rate matches what the game expects — 48000 Hz works best.
