That may helps to improve this software, although this amount of bug fixes should be better fixed in beta-versions before published as stable. However, I have no major bugs so far, I will keep using the portable version of Sumatra PDF.

I use it every day. I print PDFs and I don't notice any problems with it.

All lovely and simple, low system requirements etc. But when I used it it had a problem opening files with a password on. I had various documents from my bank in PDF form with a password and Sumatra supposedly nice because lightweight couldn't manage to open.

I had to install Adobe Acrobat Reader which is thick compared to Sumatra PDF - but opens all PDFs

Is it possible they were scripted or with links, etc? Sumatra avoids adding features, which would add vulnerabilities. I have PDFs from bank and work and they open, also tested with this.

I don't know. In my case, it's like this.
I deal with something at my bank. I get a PDF file in the mail. And a text message to my phone the password to extract.
When I had the Sumatra PDF then after entering the password the document opened but there was nothing inside.
I installed Acrobat Reader and after doing so I got a "paperclip" on the left hand side to access another PDF document that I was interested in. Maybe it's the encryption ?

Password Protect PDF - Encrypt your PDF online safely

You are not afraid to use such tools when opening documents with private content ?

It is a shame that Sumatra PDF cannot do this.
This is what I miss about it

Do you know another application than Adobe Acrobat Reader to read such files ? (encrypted) so that it is free and does not take up 700 MB on the disk. For me it is too much to read PDF files but for today it works for me.
Using the online version not acceptable

I used Sumatra in stead of Adobe in the past, but why would you need a PDF reader nowadays when browsers (with strong sandboxing and site permission restrictions) can also read PDFs?

In Windows11 Microsoft forces Edge upon people. Edge has the strongest sandbox (AppContainer) and security (SuperDupermode). I don't use Edge as the browser on my wife's laptop, but use it with all site permissions on deny as PDF reader (and you can harden Edge with registry tweaks using GPO settings, eg enable PDFSecureMode).

Alternative (to Adobe) PDF readers are (on Windows) a blast from the past IMO.

I install it just for the PDF thumbnails.

1st because not everyone does use Edge as default browser. 2nd average users doesn't harden their browsers to be stronger protected, specially for Edge via GPO.
3rd Adobe Acrobat Reader has a very large files size and some users does prefer a more lightweight software even as portable version like Sumatra PDF Reader.

Chrome with its sandbox, probably is also a safer alternative to Sumatra. Edge was just an example.
