Describe the bug

While Attempting to access FreshRSS, after entering username and password, I receive an error page that reads:

Looks like there’s a problem with this site

https://[FreshRSS]/p/i/?rid=68235b7652ca8 might have a temporary problem or it could have moved.

Error code: 500 Internal Server Error

    The site could be temporarily unavailable or too busy. Try again in a few moments.

To Reproduce

Worth noting that I was able to access the instance on Saturday. Unfortunately, I cannot recall if I updated to 126.2 then or the day before. Also of note, I am able to get to the Web form, I only get the above error after attempting to log in, normally.

Additionally, once the cookies are saved on the browser(s), I am able to access the instance's Admin page if I use:
https://[FreshRSS/p/i/?c=update

Upon doing this, I noticed in my logs a number of RSS entries that had been replicated, but I deleted those. Albeit it seems unrelated. The very last thing I did on the instance was add a feed from Youtube using Capy Reader. I am not sure if this is relevant, but I am just mentioning as a possible clue.

When I try to link back to "your RSS feeds," in the Admin page, I once again get the original error above, but my logs do not show any issue, at all, even after multiple tries. Perhaps the issue is with the 126.2 install and that it may have changed something in my config or database. However I am unsure on how to proceed.

I did have a back up in Data.bak. Replaced that into the Data folder and still got the same error as above. I followed by reverting the change to the way it was. I also had a backup of the day before, but that also yielded the same error.

When I try:
https://n.alas.click/p/api/

I get OK on both. So the API is working.
No extensions have been added or changed before this issue, either.
Tried to look up this error and could no find reference to it.

Expected behavior

To simply log in into my RSS Feed page.

FreshRSS version

126.2

Additional context

Let me know what you need. In case I missed something relevant.
Oh, one last thing, I noticed, on Capy Reader that after I updated the feed, some feeds did update. The screen on the app goes black for a second and comes back to the same as before, with no Feed newer than May 10th. Which seems to be the date when it instance broke.

On the mobile app I am able to see older feeds but that is likely because they are in the app's cache. But I am not getting errors when I try to update.

Attempted to create a new account via web form. Page comes up, but once I attempt to create new User, I get:

https://[FreshRSS]/p/i/?c=user&a=create might have a temporary problem or it could have moved.

    The site could be temporarily unavailable or too busy. Try again in a few moments.

The new user gets created though.
