Why does Low Latency Ethernet 10G MAC Intel® FPGA IP fail to relaunch MegaWizard Plug-In Manager after IP is generated?

Due to the IP renaming with Intel® Quartus® Prime software version 18.0 and 18.1, the Low Latency Ethernet 10G MAC Intel® FPGA IP can be generated successfully but it failed to reopen in MegaWizard Plug-In Manager GUI after IP generation. 

Replace the IP name "Low Latency Ethernet 10G MAC" with "Low Latency Ethernet 10G MAC Intel FPGA IP" for v18.0 and v18.1 versions in the alt_em10g32_wizard.lst file located at this path:

\ip\altera\ethernet\alt_em10g32\MAC\alt_em10g32_wizard.lst

Example:

Low Latency Ethernet 10G MAC v18.0 --> Low Latency Ethernet 10G MAC Intel FPGA IP v18.0

Low Latency Ethernet 10G MAC v18.1 --> Low Latency Ethernet 10G MAC Intel FPGA IP v18.1 

This problem is fixed beginning with the Intel® Quartus® Prime Std 19.1.
