Canon EOS RP under Linux

Canon shipped their newest and cheapest full frame camera, the Canon EOS RP, end of February. In their infinite wisdom, they decided that they had to to develop a new CR3 format for this as well as the previously released EOS R and M50 cameras. And of course, so far no one was able to reverse-engineer the raw format entirely, so it will take a good while until those cameras will be supported by all major open source raw programs out of the box. The last option is running the Adobe DNG Converter in a Windows VM or under Wine to convert the proprietary CR3 format into their (intermediate) DNG format. After a good month, Adobe released a new version that supported the RP … but it stopped working under Wine 🤦. So, whoever stumbles upon

Unhandled exception: unimplemented function api-ms-win-core-winrt-error-l1-.GetRestrictedErrorInfo called in 64-bit code

open winecfg, go to Libraries, add two entries for api-ms-win-core-winrt-error-l1-1-0 and deactivate them. The DNG converter will complain but it will work (much faster than in a Windows 10 VM!) nevertheless.
