Tor Browser Alpha and Tor Browser Stable both fail to connect to Snowflake bridges

After updating to version 15.0 or 15.0a4, I am unable to connect to Snowflake bridges. The following error is displayed:

[WARN] Can’t use bridge at [scrubbed]: there is no configured transport called “snowflake”.

I have confirmed that my antivirus software has not removed any Tor-related files, and my disk is not corrupted. The issue persists even after a fresh reinstallation.

This problem has been observed in both the stable version 15.0 and the alpha version 15.0a4.

My operating system is Windows 11.

Did you forget to turn off the proxy in connection settings when using snowflake?
