I am getting an internal error during fitter in Quartus 24.1:
Sub-system: PHYCLK, File: /quartus/periph/phyclk/phyclk_gen7.cpp, Line: 1590.
I've attached the full error message, as well as an archive of a simplified project that creates the error.
The error seems to be related to having multiple instances of the LVDS SERDES IP. The design has 4 instances of the IP block created in the design through a generate for loop. If I modify the loop to be 0..0 instead of 0..3 then compilation completes with no errors.

Hi,
Check this kdb link https://www.intel.com/content/www/us/en/support/programmable/articles/000099084.html for 24.1 patch. This internal error had been fixed in 24.2 and onwards.
Thanks,
Regards,
Sheng

Thanks for the update. No luck with cleaning the project, I am still getting the internal error.
I setup a virtual machine with Linux and 24.1 and it compiled fine, so looks like it might be an issue with Windows version. I assume you used Linux?
I also tried recompiling with different number of instances of the LVDS block by modifying the generate loop. 0..0, 0..1, 0..2 and 1..3 all compile with no issue, but 0..3 gives me the internal error.
