INTERNAL Error during WAL replay when using -ui after ALTER TABLE to ENUM type

[estndard]

I encountered an INTERNAL Error when restarting DuckDB with the -ui option. The error occurs during the WAL replay process, specifically after creating a custom ENUM type and altering a table column to use that type in a previous session.

Interestingly, this error only occurs when the -ui flag is used. When launching DuckDB without the UI option, the database loads successfully without any issues.

Repro Steps:

1. Launch DuckDB with the UI option: duckdb ondidim.duckdb -ui

2. Execute the following SQL commands:

CREATE TYPE province AS ENUM ('Seoul', 'Pusan');
CREATE TABLE office(province_name VARCHAR(20));
ALTER TABLE office ALTER province_name TYPE province;
.exit

3. Try to relaunch DuckDB with the UI option: duckdb ondidim.duckdb -ui

4. The following error appears:

INTERNAL Error: Failure while replaying WAL file "...ondidim.duckdb.wal": Calling DatabaseManager::GetDefaultDatabase with no default database set

Thanks for the report. Seems like this will require some investigation to understand what's going on.
