Fixing DaVinci Resolve Crashes Caused by Locale Settings
If DaVinci Resolve Studio crashes whenever you click a Fusion Text+ title on Linux and you're using a non-US locale (e.g. en_GB.UTF-8), the fix is simple: make sure the en_US.UTF-8 locale is actually installed and available on your system. You do not need to change your system language; it just needs to exist.
Watch the full walkthrough and fix here:
The Symptom
Resolve crashes instantly when adding a Fusion Text+ title. This commonly happens on systems set to locales that use commas for decimals (e.g. 1,25). If en_US.UTF-8 isn’t present, Fusion bails out.
The Cause
Fusion expects resources that assume a US UTF-8 locale. If en_US.UTF-8 is missing from your system’s available locales, Resolve can crash when loading Text+.
The Fix
Ensure en_US.UTF-8 Is Installed (No language switch required)
After adding en_US.UTF-8 to your available locales, Text+ works normally. No need to change your system language or wrap Resolve in LC_ALL commands; it just needs the locale to be present.
Final Thoughts
This is a straightforward environment issue: DaVinci Resolve’s Fusion relies on the US UTF-8 locale being available. Add it once and you’re done.
