Significant delay when opening Character Sheets migrated from v12 (System 0.6.x) to v13 (System 0.7.x)

I am experiencing a noticeable lag (2-4 seconds) when opening character sheets that were created in Foundry VTT v12 (system version 0.6.21) and subsequently migrated to v13. However, newly created characters in v13 (system version 0.7.11) open instantly. This lag exists for first character sheet opening after world was loaded.

So, I need an advice is there any easy way to fix this? I thought about re-importing character from character builder again, but I want to avoid this if it's possible. Do you have any better ideas?

Just checking, this is on the default system sheet? If it's a problem with my core-inspired sheet, I'd better log it over there instead.

Would you mind exporting an affected character for me to check out? I'd like to have a look at the underlying data and see if there's anything unusual in the older files.

I tried to switch between default and your core-inspired, but there is no difference about it.

Thank you! I'll check it out.

Okay, I had a look and nothing in there looks sus (well, except for a bit of html mess in an item description, but that's probably just copy & paste garbo from Google Docs—it shouldn't account for any meaningful delay). Everything else looks as I would expect.

In testing, I thought I had successfully reproduced your problem at first, but it seems for me it only happened once. I think it was probably just due to the resource links not working in my environment, so not really the same issue. Could it be that the process of importing fixed whatever was going wrong? If you haven't done so already, it might be worth trying re-importing from your export, just in case.

Issue with resource links sounds possible because I use "Quick Insert - Search Widget" module and players just import things directly from compendiums and may be that cause this lag.
I'll try to re-import, thanks!
