Crashing in late game (Ubuntu 20.04, recently started)

[SlowHands89]

I've recently started having problems more frequently with crashing out, usually 30+ minutes into the game, with a EXCEPTION_ACCESS_VIOLATION.

For example:

EXCEPTION_ACCESS_VIOLATION (0xc0000005) at address 0x0095815d
    attempted to read memory at 0x0000008f

This seems to have got dramatically worse over the last couple of weeks but I haven't been able to pinpoint it exactly, or anything that particularly changed around then. For games that don't crash, they often will upon loading the score screen if they've been longer than half an hour or so. Shorter games don't crash either during or at the score screen.

Anecdotally, there seems to be coincidence with fairly high stakes moments in the game - e.g., I play DualGap a lot and would guess it has happened multiple times when there are large bombing runs on a T4 arti.

Spec:

• i7-10750H
• 1650 Ti (Nvidia driver 450.102.04)
• 32gb ram
• Ubuntu 20.04 (Proton 5.0-10)
• Client version 1.4.2

Here is a log from another game resulting in a crash, which this time didn't really seem to coincide with anything specific. Couldn't copy the exception details this time as the pop-up for that become unresponsive when I tried to copy it.
