Loading gpx files one after the other freezes JOSM completely

[anonymous]

What steps will reproduce the problem?

1. Load a gpx file
2. Load another gpx file
3. Maybe load another gpx file

What is the expected result?

Load gpx files.

What happens instead?

1. Console log of all gpx files is be ok, this is the last one: "INFO: Open file: path.gpx (2120172 bytes) completed in 82 ms"
2. Freeze, even background auto save doesn't work (I waited long enough), thus edits are lost

If I select all gpx files at the same time, loading works, without freeze, but this isn't possible, if the gpx files are inside different folders.

Please provide any additional information below. Attach a screenshot if possible.

Just tried with some random gpx files and cannot reproduce. Can you please attach examples, thanks.

Despite that this would be a major regression, I thought, there was some option for a tree view in the file dialog added recently, probably only if "native file dialog" is used.

I don't want to upload my private ones, but I also tested the gpx files above.
Freezes after loading three gpx files.
I tested these files with completely new JOSM profile.

This patch https://josm.openstreetmap.de/attachment/ticket/21462/21462-synchronized.patch I found here https://josm.openstreetmap.de/ticket/21462 solves the problem for me. I don't know, if this is a correct fix.
