Hi, dropping in to report that I am currently facing the same issue here.
Using the same resolution (5120x1440p) Enpass chrashes on start, but freezes the PC for about 5min. I did some checking, here are my findings:
When starting Enpass, it starts to rapidly fill up the system memory. In around 20sec it fills the 32GB RAM in my machine, then everything freezes for about 3min (pink bar in screenshot). For the system, no time passes here. Afterwards, I can see that the Swap (another 32GB) are being filled up as well. Where the yellow bar is drawn, another ~1min freeze occurs. Afterwards, memory consumption drops drastically, as the OS has killed the process.
The following data can then be grabbed from dmesg:
[25921.488671] Enpass invoked oom-killer: gfp_mask=0x100dca(GFP_HIGHUSER_MOVABLE|__GFP_ZERO), order=0, oom_score_adj=0

Switching to a smaller resolution allows me to start Enpass again, however no option to send a crash report shows up.
Once Enpass is launched, I can switch resolution back to ultrawide and Enpass keeps working and is scaled perfectly.
So apparently just a problem on startup.
Edit:
When launching from the terminal, the String
gets logged exactly 185 times.
Still no dialogue to send an error report after a successful launch, even after enabling Logs. Logs reports "Nothing to show here"
