https://github.com/PrestaShop/PrestaShop/issues/39048

My problem is very similar to the mentioned report. Fresh installtion via Softaculous/Cpanel. Migrated data from PS 8.2 using Migration Pro module. Both installations are running on the same server. My default currency was SEK and when migrated all prices are in USD with the same value as I had in the old shop. 114 SEK is now 114 USD. When I try to change this I get a freeze so the web hotel manager needs to kill all processes going on.

Php 8.4 Apache 2.4.66 MariaDB 10.6.25

PrestaShop_PrestaShop_Core_Context_CurrencyContext____construct()_ Argument #5 ($numericIsoCode) must be of type string, null given, called in _home_sjostrom_public_html_shop_src_Core_Context_CurrencyContextBuilder.php on line 42 (500 Internal Server .pdf

Steps to reproduce

1 Changing default currency 2 Save, boom! 3 Stuck processes for ADMIN but not for Front office

I can do other things and get this hang-up.
