Exception: Could not find class SV\SearchImprovements\XF\Search\Source\MySqlFt when attempting to extend XF\Search\Source\MySqlFt src\XF\Extension.php

I received the following message when updating from Standard Library v1.21.10 to v1.21.11:

These sorts of errors can briefly happen when updating. But it is really bizarre that it affected a Search Improvements extension over StandardLib, you should be able to ignore it as long it doesn't repeat
